Description

Technical Field

[0001] This invention relates to the field of computer-aided drafting technology, and in particular to a method and apparatus for drawing images in computer-aided drafting. Background Technology

[0002] Computer-aided drafting (CAD) technology is an indispensable application for every engineering designer in the modern era. CAD refers to the use of drafting software and computer hardware to achieve graphic display, assist in drawing, and design. With the development of modern science and production technology, the drawings are becoming increasingly complex, placing higher demands on both accuracy and speed, making manual drafting pale in comparison. The advent of computers and plotters, along with the development of related software technologies, has enabled CAD applications to not only meet the requirements of high precision and speed but also elevate modern drafting technology to an unprecedented level.

[0003] Currently, within the domestic landscape architecture industry, CAD software is widely used by landscape designers in large, medium, and small enterprises, as well as individual designers. The most commonly used are Tianzheng Architectural CAD and ZWCAD Architectural CAD. These two CAD software programs are geared towards a broad range of design industries, including mechanical design, architectural design, interior design, and advertising design. While their various drawing functions are generally applicable and can basically meet the needs of landscape design, the existing functions of these software programs are gradually losing competitiveness in terms of the speed and quality of drawing output for design projects in the face of the ever-changing landscape industry market. Therefore, we began exploring ways to enhance our competitiveness through secondary development of the software.

[0004] While CAD software platforms offer one-click pattern fill functions for garden paths in projects, these are only for straight paths or platforms. Filling curved paths in projects requires using ZW3D's built-in manual function, drawing lines one by one based on the path's shape, length, and width to achieve concentric paving and alignment of the offset lines. This simple paving fill style can be done manually, but for more complex designs... Figure 1 The more complex paving patterns shown have more steps and take a lot of time. Summary of the Invention

[0070] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0071] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0072] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0073] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0074] Figure 2 This is a schematic flowchart illustrating a method for drawing images in computer-aided drafting, as provided in an embodiment of this application. Figure 2 As shown, the method may include the following steps:

[0075] S210, determine the target legend to be arrayed and the target array path. The target array path has radians, and the target legend corresponds to standard segments and discrete points.

[0076] The array is mainly used to create object copies arranged in a specified manner. In this embodiment, the specified manner includes arranging them according to the target array path.

[0077] The target legend is the object to be arrayed. The target legend can be paving, filling, primitives, or components, etc.

[0078] This standard segment can be a style of the target legend, such as a paving pattern. Paving pattern standard segments can be created in advance, and the paving standard segments are based on the width of the garden path to be filled, with no limit on the length.

[0079] The target array path can be a full arc or a partial arc. It is generally the center line of a road or the edges of the road.

[0080] These discrete points can be key points used to summarize the standard segment. For example, the number of discrete points can be determined by the discretization precision, which can be determined according to actual needs. For example, for standard segments with more complex structures, the discretization precision can be higher, while for standard segments with simple structures, the discretization precision can be lower. The complexity or simplicity of the structure is determined based on the types and number of graphics included in the standard segment.

[0081] The standard segment can include solid lines. The discretization precision can be determined first; then the solid lines can be discretized into discrete points according to the discretization precision.

[0082] S220, Based on the standard segment, determine the array segment to be arrayed corresponding to the target array path and the baseline of each array segment to be arrayed, wherein the baseline of the array segment to be arrayed corresponding to the array path with curvature also has curvature.

[0083] The array segment can refer to the area used to place object copies. In other words, the target array path can be divided into multiple segments based on the standard segment.

[0084] This baseline can be used to indicate the deformation of the segment to be arrayed relative to a standard segment.

[0085] S230 updates the discrete points of the target legend based on each baseline with curvature.

[0086] Based on the deformation of the baseline relative to the standard segment, the discrete points of the baseline relative to the target legend can be updated to obtain the deformed discrete points (i.e., the updated discrete points).

[0087] S240, based on the updated discrete points, fill the target legend into the segment to be arrayed.

[0088] The target legend is deformed based on the updated discrete points to obtain a deformed copy of the object.

[0089] Standard paving sections can be pre-made. The standard paving section is based on the width of the garden path to be filled, and the length is not limited. Then, select the array path (usually the center line of the road or the edge lines on both sides of the road), spacing (if the road needs to be wavy, i.e., different stones are separated, the spacing needs to be entered), and fitting accuracy (fitting accuracy for curved roads). After determining the array path, spacing, and fitting accuracy, if the selected path is the center line of the road, you can usually press the space bar to complete the layout step. This can eliminate the tedious step of manually offsetting line segments one by one according to the curved shape. You only need to prepare a small standard paving section in advance, select the center line or edge line of the curved garden path, and you can fill it with one click to achieve the concentric laying of stones in the curved garden path.

[0090] In some embodiments, the standard segment includes an outer rectangle, which has a length and a width; step S220 above may include the following steps:

[0091] Step 1): Based on the width of the standard segment, offset the target array path left and right to obtain a multi-segment line;

[0092] Step 2) Divide the multi-segment line according to the length of the standard segment to obtain the array segment. Among them, the arc with the smaller radius in the array segment is the baseline of the array. The left and right offset lines after division can be compared one by one. If there is an arc in both, the arc with the smaller radius is determined as the baseline of the array. The baselines of each segment are added together, and the sum is the total length of the array line. The total length divided by the length of the outer rectangle gives the number of standard segments in the array.

[0093] Based on this, step S230 above may specifically include the following steps:

[0094] Step 3) Align the standard segments with the corresponding segments to be arrayed according to the position of each baseline;

[0095] Step 4) Take the tangent direction of the baseline as the X-axis direction and the perpendicular direction as the Y-axis direction of the discrete points of the standard segment, and recalculate the X and Y values ​​to obtain the updated discrete points.

[0096] Based on this, step S240 above may specifically include the following steps:

[0097] Step 5) Connect the updated discrete points with lines to obtain the arrayed image.

[0098] As an example, a first settings interface can be provided, in which the standard segment and the precision of the discrete parameters can be set. For example, such as... Figure 3 As shown, the first settings interface may include a standard segment selection control. Clicking this control will jump to the standard segment selection interface, such as... Figure 4As shown, the standard segment selection interface can be an image drawing interface, where pre-drawn graphics can be selected as standard segments, or standard segments can be drawn directly from the drawing interface. For example, the first setting interface can include a standard segment selection control, which can include a standard segment selection list providing alternative standard segments for selection. This first setting interface can be displayed during the drawing process after triggering the super loft control or function. The super loft function can be triggered via a shortcut key or command.

[0099] After determining the standard segment, you can also set the discretization precision. This precision can be the number of discrete points or the density of discrete points, etc.

[0100] In some embodiments, the discrete precision can also be set based on a standard segment. For example, the first setting interface may provide a discrete precision setting control; clicking this control will take you to the discrete setting interface, such as... Figure 5 As shown, the reference segment is rectangular. The discrete settings interface can be used as an image drawing interface, displaying the graphic of the standard segment and the initial discrete points corresponding to it. This interface allows users to increase or decrease the number of discrete points, and also move their positions. Adding or deleting discrete points can be done by deleting one or more selected points, adding points near or in the middle of one or more selected points, or adding or deleting points as a whole. For example, users can input a numerical value for the number of discrete points, and the system will automatically arrange the corresponding number of discrete points on the standard segment, such as evenly distributing them. Moving the position of discrete points allows users to drag them directly, or select a discrete point and input its coordinates. Constraints can be pre-configured for the position and number of discrete points. These constraints can include a maximum and minimum number of discrete points, and the requirement that the discrete point be on the graphic, etc. Constraints can be applied when setting the position and number of discrete points.

[0101] After determining the standard segment, an array path can also be selected. For example, the first settings interface can provide an array path selection control. Clicking the control will take you to the array path selection interface, which can be an image drawing interface. In this interface, you can select a portion of a pre-drawn graphic as the array path, or draw an array path, which can include radians.

[0102] like Figure 5As shown, after determining the above information, the length and width of the outer rectangle of the standard segment can be calculated; each entity line in the standard segment is discretized into discrete points according to the input discretization precision to obtain the set of discrete points of the standard segment (including discrete points A, B, C, D, E and F).

[0103] Based on the selected path, the path can be offset left and right according to the width of the standard segment, and the offset left and right paths can be converted into PL lines. The left and right PL lines are divided according to their endpoints, and the divided left and right offset lines are compared one by one. If there are lines with arcs, the arc with the smaller radius is determined as the array baseline. The baselines of each segment are summed up, and the total length of the array lines is the total length. The total length divided by the length of the outer rectangle gives the number of standard segments in the array.

[0104] like Figure 6 As shown, the standard segments are aligned with the corresponding positions according to the position of each baseline.

[0105] like Figure 7 As shown, by taking the tangent direction of the baseline as the X-axis and the perpendicular direction as the Y-axis, the discrete points of the standard segment are recalculated to obtain new discrete points with X and Y values; for example... Figure 7 As shown, connecting the deformed discrete points with lines yields the array effect.

[0106] In some embodiments, the standard segment may include a standard graphic and gaps, the gaps being located on one or both sides of the graphic, and the size of the gaps being determined based on the construction process and the aesthetics of the drawing. The standard graphic may be a user-selected graphic that requires batch filling or array copying.

[0107] As an example, such as Figure 8 As shown, the Super Lofting function solves the problem that CAD software platforms cannot fill and achieve concentric paving of curved line segments in garden paths with one click. The Super Lofting function can eliminate the tedious steps of manually offsetting line segments one by one according to the curved shape. You only need to prepare a small standard section of paving style in advance, select the center line or edge line of the curved garden path, and you can fill it with one click to achieve concentric paving of the curved garden path stone joints.

[0108] In some embodiments, the method may further include the following steps to facilitate the arrangement of small structures.

[0109] Step A), select the blocks in the drawing;

[0110] Step B) Determine the attribute information of the attribute block and match the attribute information with the header information of the table to be generated.

[0111] Specifically, it also includes:

[0112] Step C), generate the table to be generated based on the table class; the table to be generated includes the input area and the header information, which comes from the configuration file;

[0113] Step D): In response to an input operation on the input area, the modification interface is displayed. The modification interface is used to modify the image information corresponding to the item.

[0114] Step E): After confirming that the modification of the item table is complete, store the table header information in the configuration file.

[0115] Specifically, the landscape feature layout function solves the problem of manually compiling and creating lists. You only need to use the specified information parameterized attribute blocks to pre-place points on the drawing, and then use the landscape feature layout function to count the landscape features with one click and generate a list according to the specified template.

[0116] Information feature parameterized attribute block diagram, for example Figure 9 As shown.

[0117] like Figure 10 As shown, a list template can be generated with a single click.
