Abstract

A work instruction book including required work information is accepted at an industrial site such as glass, iron plate, plywood manufacturing, and work for product manufacturing is executed on the basis of the work instruction book. The homework indicator may include an expanded view therein. The operator cuts and bends the material with reference to the expanded view of the work instruction book to manufacture a product. And the expanded drawing can be manually drawn by a designer with drawing capability. Due to the characteristic of manual work, the working speed is limited, and when drawings are drawn in a hurry within limited time, the accuracy may be reduced, so that the design work is inaccurate. The invention provides a method and a system for generating an expansion graph. The method comprises the following steps: obtaining a bending graph; generating a three-dimensional diagram based on the bending diagram; and generating an expanded graph based on the three-dimensional graph.

Description

TECHNICAL FIELD

[0001] The present application relates to a development drawing generation system and a development drawing generation method using the same. BACKGROUND

[0002] In a glass, iron plate, plywood manufacturing, and the like industrial sites, a work instruction sheet including necessary work information is received, and based on this, a work for manufacturing a product is performed.

[0003] A development drawing can be included in the work instruction sheet. A workman refers to the development drawing of the work instruction sheet to cut and bend a material to manufacture a product.

[0004] Accordingly, the writing accuracy of the development drawing can affect the quality of the product, and can also affect the waste rate in the product production process.

[0005] The development drawing can be manually drawn by a designer who can make a drawing. The development drawing can be drawn in advance with ease, or a part of the design can be changed and drawn in a short time at a site. In this case, the drawing time is urgent, and thus a problem in which the accuracy of the development drawing can be decreased can occur.

[0006] In addition, due to the characteristics of manual work, even if the drawing is drawn in the shortest time, there is a limit in the work speed thereof, and in the case in which the drawing is hastily drawn within a limited time, the accuracy thereof is decreased and an inaccurate design work can be performed.

[0007] Accordingly, in the product production work based on the development drawing, a problem in which the quality of the product to be produced can be decreased can occur, and a problem in which the waste rate in the production process can be increased can also occur.

[0031] Embodiments of the present application will be described below with reference to the accompanying drawings.

[0032] Figure 1 is a sequence diagram of a spread sheet generation method of the present application, Figure 2 is a block diagram of a spread sheet system (1000) of the present application, Figures 3 to 5 is a specific embodiment of a spread sheet generation system (1000) of the present application, and Figure 6 is an embodiment of a job instruction sheet (JQ) output by the spread sheet generation system (1000) of the present application.

[0033] The development drawing generation method of the present application can be executed in the development drawing generation system (1000) of the present application. The development drawing generation system (1000) of the present application is configured by a control section (100) and a display section (DS) that displays a drawing received from the control section (100).

[0034] The development drawing generation method of the present application is configured by the following steps: obtaining a bending drawing (BP); generating a 3D drawing (TP) based on the bending drawing (BP); and generating a development drawing (PG) based on the 3D drawing (TP).

[0035] Referring to Figure 1 and Figure 3 , in the step of obtaining the bending drawing (BP), the control section (100) can select a bending drawing (BP) that has been drawn from the outside or draw the bending drawing by hand and obtain the bending drawing (BP) by adding the bending drawing (BP).

[0036] In other words, in the development drawing generation method of the present application, the control section (100) obtains the bending drawing (BP) by inputting the bending drawing (BP) from the outside.

[0037] Referring to Figure 3 , the control section (100) transmits the obtained bending drawing (BP) to the display section (DS). The display section (DS) can display the received bending drawing (BP) in a bending drawing display area (FD1).

[0038] Specifically, the display section (DS) includes: a selection input window display area (FD4) that includes a bending drawing (BP) selection window and a bending drawing (BP) addition window in a first display window (DW1); a bending drawing display area (FD1); an elevation drawing name and quantity display area (FD2) that displays a name and a quantity of a product (Frameless Glass Door) that contains a material corresponding to the bending drawing (BP) displayed in the bending drawing display area (FD1); a product size display area (FD3) that displays a width (W) dimension, a length (H) dimension, and a material interval dimension (W1) of the product; a different section number item display area (FD5) that displays the materials contained in the product according to section numbers; a variable display area (FD6) that displays variable values in the different section number bending drawing (BP); and an elevation drawing display area (FD7) that displays the elevation drawing displayed in the different section number display area.

[0039] The development drawing generation system (1000) inputs the bending drawing (BP) from the outside through the selection input window display area (FD4). Thereby, the control section (100) obtains the bending drawing (BP) and transmits it to the display section (DS).

[0040] The display section (DS) displays the received bend drawing (BP) in the bend drawing display area (FD1), and at the same time of receiving the bend drawing (BP), the entire information of the product including the material corresponding to the bend drawing (BP) can be received. The entire information of the product can include the facade name and the number displayed in the facade name and number display area (FD2), the width dimension, the length dimension, and the material interval dimension of the product displayed in the product dimension display area (FD3), the different section itemization information displayed in the different section item display area (FD5), the variable value in the different section bend drawing (BP) displayed in the variable display area (FD6), and the facade drawing (ED) including the material corresponding to the bend drawing (BP).

[0041] Therefore, the bend drawing (BP) obtained by the display control section (100) is displayed in the bend drawing display area (FD1) of the display section (DS), and the facade name and the number of the product including the material corresponding to the corresponding bend drawing (BP) are displayed in the facade name and number display area (FD2).

[0042] The width dimension, the length dimension, and the material interval dimension of the product are displayed in the product dimension display area (FD3).

[0043] The different section itemization information itemized into the section bend drawing name, the width, the length, the number, the material, etc. according to the different section itemization is displayed in the different section item display area (FD5), and the variable value in the different section bend drawing (BP) is displayed in the variable display area (FD6). The different section itemization information and the variable value can be the stored information.

[0044] The facade drawing (ED) of the entire product including the material corresponding to the obtained bend drawing (BP) is displayed in the facade drawing display area (FD7) and the facade drawing (ED) displaying the section number is displayed.

[0045] As an example, the control section (100) can obtain the bend drawing (BP) of the section number "6" of the product (the framed glass door on the drawing). Therefore, the bend drawing (BP) corresponding to the section number "6" of the facade drawing (ED) displayed in the facade drawing display area (FD7) is displayed in the bend drawing display area (FD1) of the display section (DS). The corresponding bend drawing (BP) can have the bend drawing name "basic 12" as an example.

[0046] Next, the control section (100) performs a step of generating a 3D drawing (TP) based on the obtained bending drawing (BP). The control section (100) can transform the two-dimensional shape of the bending drawing (BP) into a three-dimensional shape based on the width dimension, the length dimension included in the bending drawing (BP). The 3D drawing (TP) based on the bending drawing (BP) is thereby generated. The control section (100) transmits the 3D drawing (TP) generated based on the bending drawing (BP) to the display section (DS).

[0047] Next, the control section (100) performs a step of generating an unfolding drawing (PG) based on the 3D drawing (TP). The control section (100) first generates the 3D drawing (TP) based on the bending drawing (BP), and generates the unfolding drawing (PG) based on the 3D drawing (TP).

[0048] The control section (100) can generate the 3D drawing (TP) based on the generation of the bending drawing (BP), and generate the unfolding drawing (PG) based on the 3D drawing (TP). Therefore, the unfolding drawing (PG) based on the dimensions of the bending drawing (BP) can be quickly generated even without separately manually drawing the unfolding drawing.

[0049] The control section (100) generates the unfolding drawing (PG) based on the dimensions reflecting the elongation ratio based on the dimensions included in the bending drawing (BP) when generating the unfolding drawing (PG) based on the 3D drawing (TP). Therefore, the unfolding drawing (PG) includes dimensions reflecting the elongation ratio based on the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension included in the bending drawing (BP).

[0050] Either of the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension of the unfolding drawing (PG) reflects the elongation ratio compared to the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension included in the bending drawing (BP), and thus the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension can be made larger or smaller.

[0051] As an example, in the unfolding drawing (PG) generated by the unfolding drawing generation system (1000) of the present application, the width direction (±Y direction on the drawing) dimension of the unfolding drawing (PG) is the same as the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension of the bending drawing (BP), and the length direction (±X direction on the drawing) dimension of a part of the plurality of bending sites can be made smaller or larger.

[0052] The unfolding drawing (PG) is a drawing used when cutting and bending a material on site, and is a drawing in which a bending site is displayed on the shape of a shape of a three-dimensional drawing unfolded on one plane.

[0053] In other words, the development drawing (PG) is a form in which the shape before bending is planarly depicted. Therefore, the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension in the development drawing (PG) should show dimensions that take into account changes in the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension of the material due to bending in the process of actually bending the material to manufacture.

[0054] The development drawing generation method of the present application, when generating a development drawing (PG) based on a 3D drawing (TP), calculates dimensions that take into account elongation based on the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension included in a bending drawing (BP) corresponding to the shape of the material actually bent, and generates a development drawing (PG). Therefore, dimensions that take into account bending of the material are marked in the development drawing (PG), and work accuracy can be improved in the process of cutting the material.

[0055] Next, the control section (100) transmits the 3D drawing (TP), the bending drawing (BP) that is the basis of the 3D drawing (TP), and the development drawing (PG) generated based on the 3D drawing (TP) to the display section (DS). The development drawing (PG) includes dimensions that take into account elongation compared to the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension included in the bending drawing (BP).

[0056] The control section (100) can simultaneously transmit work guide information when transmitting the development drawing (PG) to the display section (DS).

[0057] The work guide information includes the width direction (±Y direction on the drawing) dimension of the material, the bending start point, the bending site, the length direction (±X direction on the drawing) dimension of each section distinguished according to the bending, and the cumulative length direction (±X direction on the drawing) dimension of each section from the bending start point to the section distinguished according to the bending site. Therefore, the work guide information is displayed together in the development drawing (PG) displayed in the development drawing display region (FD9) of the display section (DS).

[0058] The width direction (±Y direction on the drawing) dimension, the length direction (±X direction on the drawing) dimension of each section distinguished according to the bending site, and the cumulative length direction (±X direction on the drawing) dimension of each section from the bending start point to the section distinguished according to the bending site included in the work guide information can be dimensions calculated taking into account elongation compared to the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension included in the bending drawing (BP).

[0059] Reference Figure 4The display section (DS) receives the 3D drawing (TP), the bending drawing (BP), and the development drawing (PG) from the control section (100), and can convert the first display window (DW1) into the second display window (DW2). The display section (DS) can include the 3D drawing display area (FD8), the bending drawing display area (FD1), and the development drawing display area (FD9) in the second display window (DW2).

[0060] The display section (DS) displays the 3D drawing (TP) received from the control section (100) in the 3D drawing display area (FD8), displays the bending drawing (BP) in the bending drawing display area (FD1), and displays the development drawing (PG) in the development drawing display area (FD9).

[0061] The display section (DS) can sequentially display the bending drawing (BP), the 3D drawing (TP), and the development drawing (PG) in the respective display areas (FD1, FD8, FD9). Alternatively, the display section (DS) can simultaneously display the bending drawing (BP), the 3D drawing (TP), and the development drawing (PG) in the respective display areas (FD1, FD8, FD9).

[0062] In the bending drawing (BP) displayed in the bending drawing display area (FD1), the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension of the material in the bent state are simultaneously displayed. In other words, the bending drawing (BP) includes the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension of the material in the bent state, and the bending start point (start on the drawing).

[0063] In the development drawing (PG) displayed in the development drawing display area (FD9), the work guide information received from the control section (100) is simultaneously displayed.

[0064] More specifically, in the development drawing (PG), the width direction (±Y direction on the drawing) dimension calculated in consideration of the elongation rate compared to the length direction (±X direction on the drawing) dimension and the width direction (±Y direction on the drawing) dimension included in the bending drawing (BP), the length direction (±X direction on the drawing) dimension of the different interval distinguished according to the bending site, and the length direction (±X direction on the drawing) dimension of the different interval accumulated from the bending start point to the interval distinguished according to the bending site are displayed.

[0065] In addition, the bending start point is displayed in characters (dots and the English word "start" on the drawing), and the bending sites are distinguished by numbers and displayed in a numbered form (for example, numbers "0 to 9"). In this case, the planar shape of the development drawing (PG) can have nine bending sites. In the case of the number "0", it can mean the bending start point (start on the drawing).

[0066] The length direction (±X direction in the figure) dimension of each section distinguished according to the bending section, and the cumulative length direction (±X direction in the figure) dimension from the bending start point to the section distinguished according to the bending section are also displayed on the expanded view (PG), and can also be displayed separately in the different bending section length display area (FD11).

[0067] As an example, the planar shape of the expanded view (PG) is distinguished by the numeral "0", and the length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the first section is 10 mm, and the cumulative length direction (±X direction in the figure) dimension can be 10 mm.

[0068] In addition, the length direction (±X direction in the figure) dimension from the first section to the second section is 114, and the cumulative length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the second section can be 124 mm.

[0069] The length direction (±X direction in the figure) dimension from the second section to the third section is 26, and the cumulative length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the third section can be 150 mm.

[0070] The length direction (±X direction in the figure) dimension from the third section to the fourth section is 12, and the cumulative length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the fourth section can be 162 mm.

[0071] The length direction (±X direction in the figure) dimension from the fourth section to the fifth section is 16, and the cumulative length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the fifth section can be 178 mm.

[0072] The length direction (±X direction in the figure) dimension from the fifth section to the sixth section is 12, and the cumulative length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the sixth section can be 190 mm.

[0073] The length direction (±X direction in the figure) dimension from the sixth section to the seventh section is 26, and the cumulative length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the seventh section can be 216 mm.

[0074] The length direction (±X direction in the figure) dimension from the seventh section to the eighth section is 114, and the cumulative length direction (±X direction in the figure) dimension from the bending start point ("start" in the figure) to the eighth section can be 330 mm.

[0075] The lengthwise (the ±X direction on the drawing) dimension from the eighth section to the ninth section is 10, and the cumulative lengthwise (the ±X direction on the drawing) dimension from the bending start point (the "start" on the drawing) to the ninth section can be 340 mm.

[0076] Referring to Figure 4 In the different bending site length display area (FD11), sections distinguished by numbers can be listed. As an example, the first section to the ninth section can be listed.

[0077] In the different bending site length display area (FD11), the lengthwise (the ±X direction on the drawing) dimension of each different section, and the cumulative lengthwise (the ±X direction on the drawing) dimension from the bending start point to each section are itemized and displayed.

[0078] The lengthwise (the ±X direction on the drawing) dimension of each different section is the same as the lengthwise (the ±X direction on the drawing) dimension displayed in the planar shape of the expanded drawing (PG), and the cumulative lengthwise (the ±X direction on the drawing) dimension to each section is the same as the cumulative lengthwise dimension from the bending start point to the first section to the ninth section respectively displayed in the planar shape of the expanded drawing (PG).

[0079] In other words, in the different bending site length display area (FD11), the lengthwise (the ±X direction on the drawing) dimension of each different section, and the cumulative lengthwise (the ±X direction on the drawing) dimension from the bending start point to each section are displayed.

[0080] The control unit (100) can perform the step of obtaining the cutting information after the step of generating the 3D drawing (TP).

[0081] Specifically, in the case where the control unit (100) does not obtain the cutting information after the step of generating the 3D drawing (TP), since there is no obtained cutting information, the expanded drawing (PG) can be generated based on the generated 3D drawing (TP), and based on the lengthwise (the ±X direction on the drawing) dimension and the widthwise (the ±Y direction on the drawing) dimension of the material included in the bending drawing (BP) to calculate the dimensions considering the elongation rate.

[0082] Differently, the control unit (100) can obtain the cutting information after the step of generating the 3D drawing (TP).

[0083] Referring to Figure 4 and Figure 5The second display window (DW2) includes a cutting information display region (FD10). The cutting information display region (FD10) includes: an upper direction cutting information display region (FD12) in which cutting information about an upper portion of a three-dimensional shape included in the 3D drawing (TP) is input; and a lower direction cutting information display region (FD13) in which cutting information about a lower portion of the three-dimensional shape is input.

[0084] The cutting information includes a cutting direction of an upper portion, a lower portion of a material of the three-dimensional shape included in the 3D drawing (TP), and a cutting angle from a reference line at the time of cutting according to the cutting direction.

[0085] Specifically, the cutting direction means a direction in which the upper portion of the material of the three-dimensional shape is cut in any one of "from the left direction to the right direction", "from the right direction to the left direction", "from the upper direction to the lower direction", or "from the lower direction to the upper direction". In addition, the cutting direction means a direction in which the lower portion of the material of the three-dimensional shape is cut in any one of "from the left direction to the right direction", "from the right direction to the left direction", "from the upper direction to the lower direction", or "from the lower direction to the upper direction".

[0086] The cutting angle means an angle that a straight line according to the cutting direction makes with respect to a reference line that is a horizontal line horizontal in the up-down direction in the three-dimensional shape.

[0087] In the upper direction cutting information display region (FD12), the cutting direction at the upper portion of the three-dimensional shape is input, and the cutting angle is input and displayed. Referring to Figure 4 and Figure 5 , as an example, the cutting direction at the upper portion of the three-dimensional shape is "from the left direction to the right direction", and the cutting angle can be 45°.

[0088] The control section (100) can obtain the cutting information input in the upper direction cutting information display region (FD12) displayed in the display section. As an example, the control section (100) can obtain the cutting direction at the upper portion of the three-dimensional shape from the left direction to the right direction, and obtain the cutting angle of 45°.

[0089] In the lower direction cutting information display region (FD13), the cutting direction at the lower portion of the three-dimensional shape is input, and the cutting angle is input and displayed. Referring to Figure 4 and Figure 5 , as an example, the cutting direction at the lower portion of the three-dimensional shape is "from the left direction to the right direction", and the cutting angle can be 45°.

[0090] The control section (100) can obtain the cutting information input in the lower direction cutting information display area (FD13) displayed in the display section. As an example, the control section (100) can obtain the cutting direction in the lower portion of the three-dimensional shape from the left direction to the right direction, and obtain the cutting angle of 45°.

[0091] Next, the control section (100) generates the 3D graph (TP) reflecting the cutting direction and the cutting angle in the upper portion of the obtained three-dimensional shape, and reflecting the cutting direction and the cutting angle in the lower portion of the obtained three-dimensional shape.

[0092] Specifically, the control section (100) can generate the 3D graph (TP) based on the width direction (±Y direction on the drawing) dimension and the length direction (±X direction on the drawing) dimension included in the bending graph (BP) and transmit to the display section (DS) in a case where the cutting information is not obtained.

[0093] The control section (100) generates the 3D graph (TP) based on the width direction (±Y direction on the drawing) dimension and the length direction (±X direction on the drawing) dimension included in the bending graph (BP) (hereinafter referred to as "basic 3D graph") in a case where the cutting information is obtained, and generates the 3D graph reflecting the cutting information (hereinafter referred to as "cutting 3D graph") based on the basic 3D graph (TP).

[0094] The control section (100) generates the cutting 3D graph (CT) which is distinguished into a first area (F1) formed by the three-dimensional shape reflecting the cutting information on the basic 3D graph (TP) and a second area (F2) corresponding to an area other than the first area (F1) among the entire area formed by the three-dimensional shape included in the basic 3D graph (TP).

[0095] The cutting 3D graph (CT) includes the three-dimensional shape which distinguishes the first area (F1) formed by the three-dimensional shape reflecting the cutting information based on the three-dimensional shape included in the basic 3D graph (TP) and the second area (F2) formed by the area other than the first area (F1) among the entire area formed by the three-dimensional shape included in the basic 3D graph (TP).

[0096] The control section (100) transmits the generated cutting 3D graph (CT) to the display section (DS).

[0097] The display section (DS) displays the cutting 3D graph (CT) which distinguishes the first area (F1) and the second area (F2) in the 3D graph display area (FD8), and can display the first area (F1) and the second area (F2) in different colors.

[0098] The control section (100) generates a cut 3D map (CT) and generates a development map (PG) corresponding to a 3D shape reflecting cut information corresponding to the first region (Fl) after the generation of the cut 3D map (CT).

[0099] The 3D shape included in the first region (Fl) is a shape generated by reflecting cut information (specifically, a cut direction and a cut angle) on a 3D shape included in a basic 3D map (TP) generated based on a width direction (±Y direction on the drawing) dimension and a length direction (±X direction on the drawing) dimension included in a bending map (BP).

[0100] Therefore, either of the width direction (±Y direction on the drawing) dimension and the length direction (±X direction on the drawing) dimension of the development map (PG) of the first region (Fl) differs from the width direction (±Y direction on the drawing) dimension and the length direction (±X direction on the drawing) dimension of the development map (PG) generated based on the 3D shape included in the basic 3D map.

[0101] As an example, the control section (100) can obtain a cut direction of an upper portion and a lower portion of the 3D shape included in the basic 3D map (TP) "from a left direction to a right direction" and obtain a cut angle of 45°.

[0102] Therefore, the dimension of the 3D shape constituting the first region (Fl) of the cut 3D map (CT) from the upper direction to the lower direction can be changed compared to the dimension of the 3D shape included in the basic 3D map (TP) from the upper direction to the lower direction. The dimension of the 3D shape included in the basic 3D map (TP) from the upper direction to the lower direction can correspond to the width direction (±Y direction on the drawing) dimension in the basic development map (PG).

[0103] The control section (100) generates a cut development map (CP) based on the 3D shape constituting the first region (Fl) and transmits it to the display section (DS). The display section (DS) displays the cut development map (CP) of the first region (Fl) in the development map display region (FD9).

[0104] Referring to Figure 5 The cut development map (CP) based on the first region (Fl) is displayed in the development map display region (FD9). Since the cut development map (CP) is a development map generated based on the first region (Fl) of the cut 3D map (CT), it differs from the basic development map (PG) in the width direction (±Y direction on the drawing) dimension or the length direction (±X direction on the drawing) dimension. In the present application, as an example, the cut development map (CP) differs from the basic development map (PG) in the width direction (±Y direction on the drawing) dimension.

[0105] As an example, the length direction (±X direction on the drawing) dimension of each different section (first section to ninth section) of the planar shape of the cutaway development drawing (CP) and the cumulative length direction (±X direction on the drawing) dimension from the bend start point to each section (first section to ninth section) can be the same as the dimension of the planar shape of the basic development drawing (PG).

[0106] On the other hand, the planar shape of the cutaway development drawing (CP), which is generated to reflect the cutting information (cutting direction and cutting angle), can differ from the width direction (±Y direction on the drawing) dimension of the planar shape of the basic development drawing (PG).

[0107] Referring to Figure 4 , the width direction (±Y direction on the drawing) dimension of each different section (first section to ninth section) of the planar shape of the basic development drawing (PG) generated based on the width direction (±Y direction on the drawing) dimension and the length direction (±X direction on the drawing) dimension included in the bend drawing (BP) without reflecting the cutting information can be 576 mm.

[0108] On the other hand, the planar shape of the cutaway development drawing (CP) generated to reflect the cutting information can be changed in dimension compared to the width direction (±Y direction on the drawing) dimension of the planar shape of the basic development drawing (PG) according to the cutting information.

[0109] Referring to Figure 5 , the width direction (±Y direction on the drawing) dimension of the bend start point (number "0" on the cutaway development drawing) of the planar shape of the cutaway development drawing (CP) can be changed compared to the width direction (±Y direction on the drawing) dimension of each different section in the basic development drawing (PG) according to the cutting information.

[0110] As an example, the width direction (±Y direction on the drawing) dimension of the bend start point (number "0" on the cutaway development drawing) of the planar shape of the cutaway development drawing (CP) can be changed to 556 mm.

[0111] The width direction (±Y direction on the drawing) dimension of the third section of the planar shape of the cutaway development drawing (CP) can be changed to 524 mm. In addition, the width direction (±Y direction on the drawing) dimensions of the fourth section to the ninth section can be changed to 524 mm, 492 mm, 492 mm, 440 mm, 140 mm, and 460 mm, respectively.

[0112] The cutaway development drawing (CP) does not include the development drawing of the second region (F2) of the cut 3D drawing (CT) but includes only the development drawing of the first region (F1).

[0113] The development drawing generation system (1000) of the present application generates a cutting 3D drawing (CT) reflecting cutting information when inputting cutting information, and generates a cutting development drawing (CP) of a three-dimensional shape deformed according to the cutting information, compared to a three-dimensional shape included in a basic 3D drawing (TP) based on a bending drawing (BP).

[0114] Therefore, the development drawing generation system (1000) of the present application can provide a development drawing (cutting development drawing (CP)) of high accuracy considering a shape according to cutting information of a material used in an actual site. This can improve the accuracy of cutting and bending work of the material and improve the efficiency of work.

[0115] On the other hand, unlike the development drawing generation system (1000) of the present application, in a case where the cutting development drawing (CP) cannot be generated, first, the material should be cut once based on a basic development drawing (PG) based on a three-dimensional shape included in a basic 3D drawing (TP) not reflecting cutting information based on the bending drawing (BP), and then a process of cutting the material according to the cutting information should be performed again. Therefore, a work process including the process of cutting the material can be cumbersome.

[0116] However, the development drawing generation system (1000) of the present application generates a cutting development drawing (CP) of a first region (F1) formed of a three-dimensional shape reflecting cutting information. Therefore, a process of cutting the material according to the cutting information after cutting the material once based on a basic development drawing (PG) based on a three-dimensional shape included in a basic 3D drawing (TP) not reflecting cutting information based on the bending drawing (BP) can not be performed, and the material can be directly cut according to the cutting information. In other words, the cutting process of the material can be more effectively simplified.

[0117] In addition, the cutting development drawing (CP) is a development drawing generated in a three-dimensional shape of the basic 3D drawing (TP) reflecting an elongation rate in a width direction (±Y direction on the drawing) size and a length direction (±X direction on the drawing) size included in the bending drawing (BP) corresponding to the first region (F1) reflecting the cutting information. Therefore, since the width direction (±Y direction on the drawing) size and the length direction (±X direction on the drawing) size of the cutting development drawing (CP) are sizes considering the elongation rate, the accuracy of work can be improved when cutting work is performed.

[0118] The control part (100) can generate a bending drawing (BP), a cutting 3D drawing (CT) reflecting cutting information and distinguished into a first region (F1), a second region (F2), a job instruction (JQ) including a cutting development drawing (CP) of the first region (F1) formed of a three-dimensional shape reflecting the cutting information after generating the cutting development drawing (CP).

[0119] Figure 6An example of a job instruction sheet (JQ) generated by the control section (100) is shown. The job instruction sheet (JQ) can be displayed in the display section (DS) and can be output.

[0120] While the application has been described with reference to the preferred embodiments thereof, it is to be understood that the application is not limited to the preferred embodiments and that modifications or variations are possible within the spirit and scope of the application as those skilled in the relevant art will readily understand from the disclosure herein.
