Description

Technical Field

[0001] The present invention relates to the technical field of architectural design, and particularly to a layout method and device for two-dimensional cutting members in an irregular plane. Background Art

[0002] Parametric design is a design method that can efficiently complete architectural design by defining variables and their logical relationships with design results. It takes algorithmic thinking as the core, deeply binds design parameters with design results. During the design process, designers only need to change some of the parameters to update the entire design result.

[0003] The layout plane of two-dimensional cutting members is diverse and liberal. During the laying process of the layout plane, except for reserved openings, the remaining areas need to be "fully covered" with member units to ensure that there are no uncovered blank areas. The member units should be connected according to the specified laying method, and the thickness of the construction joints should be kept uniform and flat. To meet the "full coverage" requirement of the irregular area, the member units should be cuttable into any shape, but complete two-dimensional cutting members should be preferably used during laying, and the two-dimensional cutting members are only cut in the boundary areas of the layout plane.

[0004] Based on this, the existing technology mainly has the following problems in the layout of two-dimensional cutting members: First, when the existing technology deals with non-irregular plane layouts, the positioning of members is relatively regular and controllable, but when facing an irregular plane with complex curved surfaces or non-regular geometric shapes, it is difficult to achieve precise positioning of member units; Second, in non-irregular plane layouts, due to the simple boundary of the layout plane, the members can easily cover the entire plane, but due to the complex curve boundary characteristics of the irregular plane, it is difficult for member units to cover the entire plane, and uncovered blanks or gaps are likely to occur; Third, when laying out non-irregular planes, due to the regular and simple layout boundaries, the members are mostly standard shapes, but when laying out irregular planes, in order to fit the complex curve boundaries, a large number of irregular cutting members will be generated in the plane edge areas, and there is a lack of a method for quickly generating irregular cutting members.

[0005] Therefore, it is necessary to provide a method for quickly generating the cutting layout of members in an irregular plane to solve the problem of difficult generation of irregular cutting members in the layout of an irregular plane. Summary of the Invention

[0006] The purpose of the present invention is to provide a layout method for two-dimensional cutting members in an irregular plane to solve the problem of difficult generation of irregular cutting members in the layout of an irregular plane.

[0007] In a first aspect, the layout method of two-dimensional cutting members in a special-shaped plane provided by the present invention includes: obtaining initialization data for laying out the special-shaped plane, where the initialization data includes layout plane data, two-dimensional cutting member data, laying constraints, and construction joint data; creating a member plane model based on the layout plane data and the two-dimensional cutting member data; calculating the geometric dimensions of the segmentation unit according to the two-dimensional cutting member data and the construction joint data; creating segmentation lines based on the member plane model, the geometric dimensions of the segmentation unit, and the laying constraints, and obtaining an orthogonal segmentation line set located in the special-shaped plane according to the member plane model and the segmentation lines; segmenting the member plane model according to the orthogonal segmentation line set to obtain member units, and instantiating the orthogonal segmentation lines according to the construction joint data to obtain model construction joints, thereby completing the cutting layout model.

[0008] The beneficial effects of the layout method of two-dimensional cutting members in a special-shaped plane provided by the present invention are as follows: An orthogonal cutting method is proposed for laying out two-dimensional cutting members in a special-shaped plane. The laying positions of the members are located by designing orthogonal segmentation lines, and closed areas are formed by horizontal and vertical intersections to determine the laying positions of each member. Applying the orthogonal cutting method proposed by the present invention for laying out two-dimensional cutting members can not only handle complex irregular layout planes but also meet the requirement of preferentially using complete member units during the layout process. It can quickly and accurately obtain the layout of two-dimensional cutting members in a special-shaped plane mainly composed of complete two-dimensional cutting members and supplemented by special-shaped member units, generate irregular members required at the edge of the special-shaped plane, achieving the effects of saving raw materials while improving design efficiency and construction accuracy. The layout method of two-dimensional cutting members in a special-shaped plane provided by the present invention can also be designed to form an intelligent algorithm for processing, realizing the intelligent generation of the layout design of two-dimensional cutting members, and further improving the layout efficiency of two-dimensional cutting members.

Obtain the set of orthogonal dividing lines located within the irregular plane according to the component plane model and the dividing lines, including: obtaining the layout plane data to determine the maximum and minimum values of the outer contour line on the coordinate axes based on the outer contour line of the plane to be laid out and the global coordinates, and generating an envelope rectangle that envelopes the plane to be laid out; obtaining the laying constraints to get the laying starting point, taking the laying starting point as the center, extending and arranging horizontal dividing lines along the set laying direction, obtaining the width of the dividing unit as the spacing between the dividing lines, and creating dividing lines parallel to the horizontal dividing lines until the envelope rectangle is filled with dividing lines to obtain the set of horizontal dividing lines; creating a set of vertical dividing lines according to the set laying method, and the set of horizontal dividing lines and the set of vertical dividing lines form the set of dividing lines; judging whether the dividing lines in the set of dividing lines are located within the plane to be laid out according to the component plane model and the set of dividing lines. When the dividing line is located within the plane to be laid out, retain the dividing line, and the retained dividing lines form the set of orthogonal dividing lines.

[0013] Create a set of vertical dividing lines according to the set laying method, including: when the set laying method is the continuous straight laying type, taking the laying starting point as the center, creating dividing lines perpendicular to the dividing lines in the set of horizontal dividing lines to form the set of vertical dividing lines; when the set laying method is the offset straight laying type, taking the laying starting point as the center, and obtaining the width of the dividing unit as the length of the dividing line, creating odd-row vertical dividing lines perpendicular to the dividing lines in the set of horizontal dividing lines, obtaining the length of the dividing unit as the spacing between the odd-row dividing lines, translating along the laying direction based on the position line of the odd-row vertical dividing lines the length of the dividing unit, and then translating the width of the dividing unit in the direction perpendicular to the laying direction to obtain the even-row dividing lines. The odd-row vertical dividing lines and the even-row vertical dividing lines form the set of vertical dividing lines.

[0014] Judge whether the dividing lines in the set of dividing lines are located within the plane to be laid out according to the component plane model and the set of dividing lines. When the dividing line is located within the plane to be laid out, retain the dividing line, including: obtaining all the vertex coordinates of the component plane model; selecting any point P on the horizontal dividing line, extending a ray in the left and right directions starting from point P, calculating the number of intersection points F between the ray and the component plane model. When F = 0, it means the dividing line is outside the plane to be laid out and delete the dividing line. When F is odd, delete the intersection points that coincide with the vertices of the component plane model of the ray and obtain the X coordinates of the remaining intersection points. When F is even, obtain the X coordinates of all the intersection points between the ray and the component plane model, arrange the obtained X coordinates in ascending order, and then match the intersection points in pairs to form a set of line segments, judge whether the set of line segments coincides with the dividing lines in the set of dividing lines, and retain the coincident dividing lines; select any point on the vertical dividing line , starting from a point extend a ray in the up and down directions, and calculate the number of intersection points of the ray and the component plane model , when = 0, it means that the dividing line is outside the layout plane, and the dividing line is deleted. When is odd, delete the intersection point where the ray coincides with the vertex of the component plane model and obtain the Y coordinates of the remaining intersection points. When is even, obtain the Y coordinates of all intersection points of the ray and the component plane model. After arranging the obtained Y coordinates from small to large, match the intersection points in pairs to form a set of line segments, and determine whether the line segments in the set of line segments coincide with the dividing lines in the dividing line set, and retain the coincident dividing lines.

[0024] Among them, the two-dimensional cutting member data is the data of the complete member unit used during the layout of the layout plane. When laying out the special-shaped plane, it is preferred to use the complete member unit for layout.

[0025] S102: Create a member plane model based on the layout plane data and the two-dimensional cutting member data.

[0026] In a possible embodiment, creating a member plane model based on the layout plane data and the two-dimensional cutting member data includes: obtaining the layout plane data, creating a geometric entity according to the outer contour line of the plane to be laid out; setting the thickness and material of the geometric entity to the thickness and material of the two-dimensional cutting member according to the two-dimensional cutting member data to obtain the member plane model.

[0028] In a specific embodiment, calculating the geometric dimensions of the segmentation unit according to the two-dimensional cutting member data and the construction joint data includes: calculating the length of the segmentation unit as the sum of the length of the two-dimensional cutting member and the construction joint thickness; calculating the width of the segmentation unit as the sum of the width of the two-dimensional cutting member and the construction joint thickness.

[0029] S104: Create a segmentation line based on the member plane model, the geometric dimensions of the segmentation unit, and the laying constraints, and obtain an orthogonal segmentation line set located within the special-shaped plane according to the member plane model and the segmentation line.

[0030] In a possible embodiment, obtain the maximum and minimum values of the outer contour line of the plane to be laid out in the X-axis direction and the Y-axis direction, and then form a minimum coordinate point (x min , y min ) composed of the minimum value in the X-axis direction and the minimum value in the Y-axis direction and a maximum coordinate point (x max , y max ) composed of the maximum value in the X-axis direction and the maximum value in the Y-axis direction, and generate an envelope rectangle that can envelope the entire plane to be laid out based on the minimum coordinate point and the maximum coordinate point.

[0031] In a possible embodiment, a dividing line is created based on the component plane model, the geometric dimensions of the dividing unit, and the laying constraints. An orthogonal dividing line set located within the irregular plane is obtained according to the component plane model and the dividing line, including: obtaining the layout plane data to determine the maximum and minimum values of the outer contour line on the coordinate axes based on the outer contour line of the plane to be laid out and the global coordinates, and generating an envelope rectangle that envelopes the plane to be laid out; obtaining the laying constraints to obtain the laying starting point, centering on the laying starting point, extending and arranging horizontal dividing lines along the set laying direction, obtaining the width of the dividing unit as the spacing between the dividing lines, and creating dividing lines parallel to the horizontal dividing lines until the envelope rectangle is filled with dividing lines to obtain the horizontal dividing line set; creating a vertical dividing line set according to the set laying method, and the horizontal dividing line set and the vertical dividing line set form the dividing line set; judging whether the dividing lines in the dividing line set are located within the plane to be laid out according to the component plane model and the dividing line set, and retaining the dividing lines when the dividing lines are located within the plane to be laid out, and the retained dividing lines form the orthogonal dividing line set.

[0032] In a specific embodiment, refer to the attached drawings of the specification Figure 4 , creating a vertical dividing line set according to the set laying method, including: when the set laying method is the continuous straight laying type, centering on the laying starting point, creating dividing lines perpendicular to the dividing lines in the horizontal dividing line set to form the vertical dividing line set; when the set laying method is the staggered straight laying type, centering on the laying starting point, and obtaining the width of the dividing unit as the length of the dividing line, creating odd-row vertical dividing lines perpendicular to the dividing lines in the horizontal dividing line set, obtaining the length of the dividing unit as the spacing between the odd-row dividing lines, and translating the length of the dividing unit along the laying direction based on the position line of the odd-row vertical dividing lines, and then translating the width of the dividing unit in the direction perpendicular to the laying direction to obtain the even-row dividing lines, and the odd-row vertical dividing lines and the even-row vertical dividing lines form the vertical dividing line set.

[0033] When the laying method is the continuous straight laying type, the spacing between the vertical dividing lines is the width of the dividing unit. When the laying method is the staggered straight laying type, the spacing between the odd-row dividing lines and the spacing between the even-row dividing lines are both the length of the dividing unit, and the spacing between the two closest dividing lines belonging to two adjacent odd and even rows is the length of the dividing unit, and such a setting can meet the engineering requirement of "offset joint".

[0034] In a specific embodiment, it is determined whether the dividing lines in the set of dividing lines are located within the plane to be laid out according to the component plane model and the set of dividing lines. When the dividing line is located within the plane to be laid out, the dividing line is retained, including: obtaining all vertex coordinates of the component plane model. Select any point P on the horizontal dividing line, extend a ray in the left and right directions starting from point P, and calculate the number of intersection points F between the ray and the component plane model. When F = 0, it means the dividing line is outside the plane to be laid out and the dividing line is deleted. When F is odd, delete the intersection points where the ray coincides with the vertices of the component plane model and obtain the X coordinates of the remaining intersection points. When F is even, obtain the X coordinates of all intersection points between the ray and the component plane model. After arranging the obtained X coordinates in ascending order, pair up the intersection points to form a set of line segments, and determine whether the set of line segments coincides with the dividing lines in the set of dividing lines, and retain the coincident dividing lines; select any point on the vertical dividing line , starting from point , extend a ray in the up and down directions, and calculate the number of intersection points between the ray and the component plane model. When = 0, it means the dividing line is outside the plane to be laid out and the dividing line is deleted. When is odd, delete the intersection points where the ray coincides with the vertices of the component plane model and obtain the Y coordinates of the remaining intersection points. When is even, obtain the Y coordinates of all intersection points between the ray and the component plane model. After arranging the obtained Y coordinates in ascending order, pair up the intersection points to form a set of line segments, and determine whether the set of line segments coincides with the dividing lines in the set of dividing lines, and retain the coincident dividing lines.

[0035] Exemplarily, select any point P on a horizontal dividing line, extend a ray in the left and right directions starting from point P, and calculate the number of intersection points F between the ray and the component plane model. When F = 0, it means the dividing line is outside the plane to be laid out and the dividing line is deleted. When F is odd, delete the intersection points where the ray coincides with the vertices of the component plane model and obtain the X coordinates of the remaining intersection points. When F is even, obtain the X coordinates of all intersection points between the ray and the component plane model. Arrange all the obtained X coordinates in ascending order as the set (x1,..., x n ), where x1 <... < x n . Connect the intersection points in the set in pairs to form straight line segments, that is, connect x1 and x2, x3 and x4, and so on. Determine the overlapping part between the straight line segments formed by the intersection points and the dividing lines in the set of dividing lines, and retain the overlapping dividing lines. Perform the above judgment process on all horizontal dividing lines in turn to obtain the set of retained horizontal dividing lines.

[0036] Select any point on the vertical dividing line , starting from point Extend a ray in the up and down directions starting from a starting point, and calculate the number of intersection points of the ray and the component plane model. When = 0, it means that the dividing line is outside the plane to be laid out, and the dividing line is deleted. When is odd, delete the intersection points where the ray coincides with the vertices of the component plane model and obtain the Y coordinates of the remaining intersection points. When is even, obtain the Y coordinates of all intersection points of the ray and the component plane model. Arrange all the obtained Y coordinates in ascending order as a set (y1,..., y n ), where y1 <... < y n . Connect the intersection points in the set in pairs to form line segments, that is, connect y1 and y2, connect y3 and y4, and so on. Judge the overlapping parts of the line segments formed by the intersection points and the dividing lines in the dividing line set, and retain the overlapping dividing lines. Perform the above judgment process on all vertical dividing lines in turn to obtain the set of retained vertical dividing lines.

[0037] The set of retained horizontal dividing lines and the set of retained vertical dividing lines form an orthogonal dividing line set.

[0038] S105: Divide the component plane model according to the orthogonal dividing line set to obtain component units, instantiate the orthogonal dividing lines according to the joint data to obtain model joints, and complete the cutting layout model.

[0040] In a possible embodiment, after obtaining the cutting layout model, it further includes: calculating the area of each component unit according to the cutting layout model, and calculating the total area of all component units; establishing a detailed list of component area information according to the area of each component unit and the total area information of all component units. The detailed list of component area information can be used as accurate reference data for material consumption, and can provide reference for the procurement and planning in the actual engineering materials.
