Description
Technical Field
[0001] The invention relates to the technical field of computer-aided design software drawing for architectural design, and in particular to a method for quickly drawing and marking triangular plates based on CAD. Background Art
[0002] In the field of building construction design technology, with the improvement and popularization of the concept of architectural art, various advanced and special-shaped structures and designs are often displayed in the society by splicing multiple conventional small structural shapes into special-shaped and advanced structures, especially in the construction process of curtain wall projects, involving hyperbolic anisotropic skylights, which are often simulated by triangular plates. The skylights have complex shapes and many types of plates, with more than thousands of triangular plates of different specifications. In addition, during the actual construction on site, the on-site error of the steel structure of the skylight is large, and the theoretical data cannot be used as a reference. The processing drawings are drawn based on the on-site measured data. In the traditional process of drawing the processing drawings of triangular plates, the bottom edge needs to be drawn according to the size, and it takes more than 30 seconds to draw a triangle. The process is cumbersome and there are many repetitive operations. It relies on manual drawing, with poor accuracy, time-consuming and labor-intensive, and low efficiency. Summary of the invention
[0003] In view of the problems that software is used to draw triangles in existing building construction designs, the drawing process is cumbersome, there are many repetitive operations, and the efficiency is low, the present invention provides a CAD triangle plate fast drawing and marking method.
[0004] The purpose of the present invention is to provide a method for quickly drawing and annotating CAD triangle plates, which solves the problem that the existing CAD software is inefficient and takes a long time to draw triangle graphics, and can achieve the technical effect of drawing multiple triangles in 5 seconds.
[0005] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:
[0006] A method for quickly drawing and marking a triangular plate based on CAD includes the following steps:
[0007] Step 1: Input the written alignment and annotation function module and circle intersection function module program codes into the CAD system and save them to form a call command, so as to facilitate repeated calls of the main program;
[0008] The alignment and annotation function module is a program that automatically calculates the positioning point based on the two measurement points passed in, and calls the alignment and annotation through these three points to automatically complete the dimensioning and positioning;
[0009] The circle intersection function module is a program that automatically calculates the point with a larger Y value among the intersection points according to the circle primitive name passed in, and returns the point coordinate value;
[0010] Step 2: Use the alignment annotation function module to select the starting point for placing the graphic, select the second point, use the first point as a reference, and calculate the direct distance L between the two points. The subsequent drawings use the starting point as the base point, L as the modulus, and the multiple increases so that the distances between the starting points of each graphic are the same.
[0011] Step 3: Filter through the program to ensure that the program only selects text primitives and counts the number of primitives n, and introduces parameter i, the default value of which is 0;
[0012] Step 4: According to the number of statistical primitives n, the following steps are repeated n times: 1) read primitive information; 2) list the read primitive information and put it into the selection set; 3) introduce parameter i and assign a value;
[0013] Step 5: Sort the selected points by their X coordinates from small to large and their Y values from large to small;
[0014] Step 6, introduce parameter k, the initial value is 0; introduce parameter j, the initial value is 3; group the introduced parameter j data into groups of 4, corresponding to the number, bottom side length, left side length, and right side length respectively;
[0015] Step 7: According to the number of statistical primitives n, draw n triangles at equal intervals repeatedly n times and mark the side lengths of the n triangles;
[0016] Step 8: After all data processing is completed, object snap is turned on and the function ends.
[0017] Furthermore, the program codes of the alignment and marking function module and the circle intersection finding function module in step 1 are all written by ourselves.
[0018] Furthermore, the step 2 requires manually setting the placement starting point and layout spacing of the drawing graphics through a mouse or keyboard, and the spacing is greater than the length of the bottom edge.
[0019] Furthermore, in step 3, a filtering condition is added to the selection process to select text, and the text needs to be placed according to the left-aligned principle when inserted.
[0020] Furthermore, the reading of graphic element information in step 4 includes reading the i-th graphic element, reading the text insertion point, and reading the text content; the listing of the read graphic element information and placing it into a selection set includes serializing the read text insertion point coordinates and text content, placing them into a selection set, and executing them in sequence; the assignment of the introduced parameter i includes assigning i=i+1, determining whether i is less than n, and if it is greater than n, the program runs downward; and: when i is less than n, repeating 1) to 3) of this step 4.
[0021] Furthermore, in step 4, all data are processed and serialized with text insertion points and content to facilitate data grouping and sorting in the next step.
[0022] Further, the step 7 comprises the following steps:
[0023] 1) Take the starting point as the origin and translate the point pt horizontally to the right by a distance of k*L as the starting point of the triangle;
[0024] 2) Take out the j-3th element (four elements are grouped together, take the first element) as the number;
[0025] 3) Take out the j-2th element (four elements are grouped together, take the second element) as the length of the base;
[0026] 4) Take out the j-1th element (four elements are grouped together, take the third element) as the length on the left;
[0027] 5) Take out the jth element (four elements are grouped together, take the fourth element) as the length of the right side
[0028] 6) Taking pt as the base point, translate horizontally to the right by the length of the bottom edge to obtain the second point of the bottom edge pd;
[0029] 7) Draw a circle with point pt as the center and the length of the left side as the radius; draw a circle with point pd as the center and the length of the right side as the radius;
[0030] 8) Using two circles as parameters, call the circle intersection function to calculate the vertex pj;
[0031] 9) Call the polyline drawing command and draw a triangle according to pt, pd, pj, pt;
[0032] 10) Call the alignment annotation function module to mark the three side lengths respectively;
[0033] 11) Delete two circles;
[0034] 12) Assign j=j+3, k=k+1, and determine whether j is less than n / 4. If j is greater than n / 4, the program will continue; and: if j is less than n / 4, repeat steps 1) to 12).
[0035] Furthermore, the steps 1) to 12) group the metadata of each graphic element, and each group of data consists of 4 data, corresponding to the number, base length, left length, and right length respectively; the data of each triangle needs to be counted in the order of this information.
[0036] Furthermore, in step 7, the program automatically assigns corresponding parameters according to the input metadata of each graphic element, automatically solves the position of each point of the triangle, automatically draws, automatically labels, and automatically deletes redundant graphics.
[0037] Furthermore, the self-written program code of the polyline drawing command in step 7 is then written into the CAD system to form a new calling command or the polyline drawing command provided by the CAD system is used to facilitate repeated calling.
[0038] Compared with the prior art, the present invention has the following beneficial effects:
[0039] 1. The present invention is based on AutoCAD software (hereinafter referred to as CAD). By saving the program codes of the self-written alignment and annotation function module and the circle intersection function module and inputting them into the CAD software to form a newly created definition command, a new CAD function module is formed to achieve batch drawing and batch annotation of triangular anisotropic plates of various sizes and shapes, which can greatly reduce the workload of designers and improve design work efficiency and work accuracy.
[0040] 2. The present invention draws the return scale data of the triangle as needed, takes the starting point as the origin, arranges the starting points of each triangle at equal distances from left to right, and groups the data of each triangle (including number, base length, left length, and right length). The alignment and annotation function module can automatically calculate the positioning point through two measuring points and annotate the side length; then, through the circle intersection function module, a circle is drawn according to the starting point and end point of the base of the triangle as the center of the circle, and the left and right lengths are used as the radius to obtain the vertices of the triangle; after determining the vertices, the triangle is drawn by calling the multi-segment drawing command; after determining the vertices, the three sides of the triangle are drawn by calling the multi-segment drawing command; then the three sides of the triangle are dimensioned by the alignment and annotation function module; the drawing and dimensioning of multiple (hundreds, thousands, tens of thousands of different sizes) triangles can be completed at the same time, which solves the problems of low efficiency, slow speed, and high workload error rate of traditional drawing methods, and has the technical effect of batch drawing and batch annotation of heterogeneous plates at the same time; it can greatly reduce the workload of designers and improve the design work efficiency and work accuracy.

[0047] To make the purpose, technical solutions and advantages of the present invention more clear, the following will be combined with the attached Figure 1-6 The embodiments of the present invention are described in further detail.
[0048] Example 1, see attached Figure 1-6 describe;
[0049] A method for quickly drawing and marking a triangular plate based on CAD includes the following steps:
[0050] Step 1: Write the program code of the alignment and marking function module and the circle intersection function module by yourself;
[0051] Input the written alignment and annotation function module and circle intersection function module program codes into the CAD system and save them to form a call command tr3, so as to facilitate repeated calls of the main program;
[0052] like Figure 1 As shown, the alignment and annotation function module is a program that automatically calculates the positioning point based on the two measurement points passed in, and calls the alignment and annotation through these three points to automatically complete the dimensioning and positioning;
[0053] like Figure 2 As shown, the circle intersection function module is a program that automatically calculates the point with a larger Y value among the intersection points according to the circle primitive name passed in, and returns the point coordinate value;
[0054] Step 2. Manually use the mouse or keyboard to use the alignment annotation function module to set the starting point and layout spacing L of the drawing graphics, and the spacing L must be greater than the length of the bottom edge. Then select the starting point for the graphics, select the second point, and use the first point as a reference to calculate the direct (straight line) distance L between the two points. The subsequent drawing takes the starting point as the base point, L is the modulus, and the multiple increases, and the distances between the starting points of each graphic are the same;
[0055] Step 3: Figure 3 As shown, through program filtering, the selection process adds filtering conditions to select text, and the text needs to be placed according to the left-aligned principle when counting; then select the text primitive and count the number of primitives n, introduce parameter i, and the default value is 0;
[0056] Step 4: According to the number of statistical primitives (such as 10-200 triangles), repeat the following steps 10-200 times:
[0057] 1) Read the i-th graphic element, read the text insertion point, and read the text content; 2) Serialize the read text insertion point coordinates and text content, put them into the selection set, and execute them in sequence; 3) Assign i=i+1, determine whether i is less than n, if it is greater than n, the program runs downward; and: when i is less than n, repeat steps 1) to 3).
[0058] or:
[0059] 1) Read the 5th graphic element, read the text insertion point, and read the text content; 2) Serialize the read text insertion point coordinates and text content, put them into the selection set, and execute them in sequence; 3) Assign i=5+1. At this time, i is greater than n, and the program runs downward.
[0060] Preferably, this step processes all data to form a serial structure with text insertion points and content, which is convenient for the next step of data grouping and sorting.
[0061] Step 5: Sort the selected points by their X coordinates from small to large and their Y coordinates from large to small;
[0062] Step 6: Figure 3 , 4 As shown in , 5, introduce parameter k, the initial value is 0; introduce parameter j, the initial value is 3; group the introduced parameter j data, each 4 as a group, corresponding to the number, bottom side length, left side length, and right side length respectively;
[0063] Step 7. Reference Figure 5-6 As shown, according to the number of statistical primitives, such as 10-200, repeat 1 and perform the following steps 0-200 times:
[0064] 1) Take the starting point as the origin and horizontally translate to the right by k*L (or 1*2500mm, 10 to 200*2500mm) as the starting point of the triangle;
[0065] 2) Take out the j-3th element (four elements are grouped together, take the first element) as the number, such as bl-01;
[0066] 3) Take out the j-2th element (four elements are grouped together, take the second element) as the base length, such as 1980.97;
[0067] 4) Take out the j-1th element (four elements are grouped together, take the third element) as the length on the left, such as 1545.1;
[0068] 5) Take out the jth element (four elements in a group, take the fourth element) as the length of the right side, such as 1593.26
[0069] 6) Taking pt as the base point, translate horizontally to the right by the length of the bottom edge to obtain the second point of the bottom edge pd;
[0070] 7) Draw a circle with point pt as the center and the length of the left side as the radius; draw a circle with point pd as the center and the length of the right side as the radius;
[0071] 8) Using two circles as parameters, call the circle intersection function to calculate the vertex pj;
[0072] 9) Call the polyline drawing command and draw a triangle according to pt, pd, pj, pt;
[0073] 10) Call the alignment annotation function module to mark the three side lengths respectively;
[0074] 11) Delete two circles;
[0075] 12) Assign j=j+3, k=k+1, and determine whether j is less than n / 4. If j is greater than n / 4, the program will continue; and: if j is less than n / 4, repeat steps 1) to 12).
[0076] Furthermore, the steps 1) to 12) group the 10-200 primitive data, each group of data consists of 4 data, corresponding to the 10-200 group numbers, bottom side length, left side length, and right side length respectively; the 10-200 triangle data need to be counted in the order of this information.
[0077] Furthermore, in step 7, the program automatically assigns corresponding parameters according to the 10-200 graphic elements read in, automatically solves the positions of each point of the 10-200 triangles, automatically draws, automatically labels, and automatically deletes redundant graphics.
[0078] Furthermore, the self-written program code of the polyline drawing command in step 7 is then written into the CAD system to form a new calling command or the polyline drawing command provided by the CAD system is used to facilitate repeated calling.
[0079] Step 8. After all data processing is completed, turn on object snap and the function ends.
[0080] The triangle data mentioned in the embodiments of the present application can be complex and irregular, and can adapt to the processing of various triangle plates. Using the above-mentioned CAD-based triangle plate rapid drawing and annotation method, the specific operation steps in the CAD interactive interface are as follows: Enter the tr3 command in the command line → Select basic data → Select the layout starting point → Select the second point → Spacebar to complete the drawing; The present invention draws the triangle return scale data as needed, takes the starting point as the origin, arranges the starting point of each triangle at equal distances from left to right, and groups the data of each triangle (including numbering, bottom side length, left side length, right side length), and the alignment annotation function module can automatically calculate the positioning point through two measuring points and annotate the side length; then, the circle intersection function module is used to calculate the alignment point according to the triangle. The starting point and end point of the bottom edge are the center of the circle respectively, and the left and right sides are used as the radius to draw a circle to obtain the vertices of the triangle; after determining the vertices, the three sides of the triangle are drawn by calling the multi-segment drawing command; and the three sides of the triangle are dimensioned through the alignment and annotation function module; the drawing and dimensioning of multiple (tens, hundreds, thousands, tens of thousands of different sizes) triangles can be completed at the same time, which solves the problems of low efficiency, slow speed, and high workload error rate of traditional drawing methods, and has the function of batch drawing and batch annotation of heterogeneous plates at the same time; it can greatly reduce the workload of designers and improve the technical effect of design work efficiency and work accuracy. The demonstration process of the present invention is as follows Figure 5-6 As shown, taking 10 groups of data as an example, the dimensions and angles are different. Enter the command tr3 → select the data information for drawing a triangle (10 groups of data include number, base length, left length, and right length) → select the layout starting point (generally select the middle position of the CAD drawing area) → select the layout spacing L (the layout spacing for this project is 2500mm) → leave space to complete the drawing. This method takes about 5 seconds in total; the traditional method takes about five to ten minutes, which greatly improves the design work efficiency. In addition, the program automatically calculates, draws and annotates throughout the process, with the characteristics of high precision and high efficiency, providing strong support for designers to carry out high-quality work.
[0081] Example 2, reference Figure 1-6 describe;
[0082] During the drawing process of the processing drawing of the special-shaped skylight for a certain project, there was a lot of data. According to the size data of the first batch of 100 triangle figures returned on site, it took a whole day of work, which was time-consuming and labor-intensive, and the efficiency was low. Under this background, a batch drawing automatic annotation program was developed. The second batch of 150 triangle size data was drawn in less than 30 seconds, which greatly reduced manual work. The program batch processing greatly improved work efficiency and work accuracy; the specific implementation steps are as follows:
[0083] 1. Load the tr3 program in the cad command;
[0084] 2. Take the second batch of returned data 150 as an example, a total of 600 data and n = 600; (the first batch uses the traditional drawing method, 100 triangles and 400 data, the drawing process takes a whole day)
[0085] 3. Enter the command tr3 → select the data information of the triangle (600 groups of triangle data including number, base length, left length and right length) → select the layout starting point (usually the middle position or the left position of the center of the CAD drawing area) → select the layout spacing L (the layout spacing of this project is 3000mm) → space to complete the drawing;
[0086] 4. The whole process is automatically drawn, which takes about 30 seconds;
