Description

Technical Field

[0001] The present invention relates to the technical field of visual modeling, and in particular to a parametric drawing method of a building facade seam diagram based on Grasshopper, a computer device and a storage medium. Background Art

[0002] In architectural design, the building facade joint diagram is often designed based on the building facade outline and doors and windows, combined with the mechanical properties of the materials and architectural aesthetics. The traditional drawing method is manual drawing through the Autodesk Autocad software platform. However, the traditional manual drawing of the building facade joint diagram often requires tedious calculations and a lot of time, and it is difficult to foresee the overall effect after the joint diagram is drawn. The traditional drawing method is not only slow in drawing speed, but also leads to a large number of repeated calculations and modifications in the later optimization and adjustment process, which makes the drawing time cycle long and the work efficiency low.

[0003] Grasshopper is a visual modeling plug-in that runs on the Rhino platform. It is a parametric modeling plug-in that generates models by programming algorithms. It models through the basic logic of input, calculation processing and output, providing a convenient and efficient way for architectural designers to use programming to build models. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a parametric drawing method of building facade seam diagram based on Grasshopper.

[0005] The technical solution adopted by the present invention is: the present invention provides a parametric drawing method of a building facade seam diagram based on Grasshopper, comprising the following steps:

[0006] S1: Pick up the horizontal outline of the building;

[0007] S2: Input the basic parameters of the building facade, including the number of building floors F, building floor height H, beam height h, odd-numbered floor joint spacing w1, even-numbered floor joint spacing w2, horizontal joint width w3, and vertical joint width w4;

[0008] S3: According to the number of building floors F and the building floor height H, the inter-floor line is obtained;

[0009] S4: According to the beam height h, the beam line is obtained;

[0010] S5: Generate horizontal slits V1 according to the transverse slit width w3;

[0014] S9: Generate vertical split seams V2 according to the vertical seam width W4;

[0015] S10: Bake the generated horizontal seams V1 and vertical seams V2 in corresponding layers.

[0016] As a preferred embodiment, in step S3, according to the number of building floors F and the building floor height H, the picked building transverse contour lines are arranged according to the arithmetic progression a n =(n-1)H for offset, where n=F, to obtain the interlayer line.

[0017] As a preferred implementation, in step S4, the interlayer line is offset vertically, and the offset is equal to the beam height h to obtain the beam line.

[0018] As a preferred implementation, in step S5, the obtained interlayer lines and beam lines are offset according to the transverse seam width w3, and the offset is equal to the seam width w3, so as to generate a horizontal split seam V1.

[0019] As a preferred implementation, in step S8, according to the odd-numbered layer slit spacing w1 and the even-numbered layer slit spacing w2, the vertical contour lines are offset according to the slit spacings to obtain odd-numbered layer slits and even-numbered layer slits.

[0020] As a preferred embodiment, in the step S9, vertical slits V2 are generated according to the vertical slit width W4 by alternating odd-numbered layers and even-numbered layers of slits.

[0021] As a preferred implementation method, when the building facade plan needs to be adjusted, by adjusting the parameters of the building storey F, building storey height H, beam height h, odd-numbered layer joint spacing w1, even-numbered layer joint spacing w2, horizontal joint width w3, and vertical joint width w4, the adjusted facade joint diagram model Vx with different characteristics is obtained.

[0022] The present invention also provides a computer device, which includes a memory and a processor, wherein a computer program is stored in the memory, and when the processor executes the computer program, the parametric drawing method of the building facade seam diagram based on Grasshopper as described above is implemented.

[0023] The present invention also provides a storage medium, wherein the storage medium stores a computer program, and when the computer program is executed by a processor, the parametric drawing method of a building facade seam diagram based on Grasshopper as described above is implemented.

During the modification process of the building facade joint diagram, the corresponding parameters can be directly adjusted to change the effect of the facade joint diagram.

[0026] Secondly, the present invention breaks through the traditional manual modeling technology and applies the writing of visual compilation programs to the drawing of building facade joint diagrams, which not only improves the modeling speed and accuracy and the drawing efficiency, but also avoids a large number of repeated calculations as the building facade plan is adjusted and modified in the later stage. The model can be quickly modified by directly adjusting the parameters in the program, which reduces the designer's work cost, greatly improves the work efficiency of the architectural design industry, and provides designers with a set of effective drawing methods.
