Study on Unfolded Drawing of Intersection Line of Cylinders Based on Computer Modeling
Compared to the method of unfolding the intersecting lines of curved surfaces in descriptive geometry,a more practical method for solving the unfolding diagram was explored by using computer technology.At the level of computer aided design(CAD)technology,a three-dimensional model of cylindrical intersecting bodies is constructed along with separated intersecting lines and extracted spatial data.At the level of scientific data processing technology,MATLAB is applied to complete the main steps of importing data,point by point sorting,coordinate transformation,and generating data of intersecting line,and the planar unfolded drawings of the main and branch pipes separately.At the feasibility technical level,based on scaled model,validation of the intersecting body and intersecting lines of the main and branch pipes are carried out,indicating the feasibility of the method proposed in the paper,which is summarized as the computer modeling method.By fully utilizing the modeling advantages of AutoCAD and the scientific calculation advantages of MAT-LAB,the correct solution process of cylinder intersection lines has been achieved,demonstrating its good technical and practical capabil-ities.It can provide practical solutions for the processing and production of intersection lines in the architectural steel structure engineer-ing,as well as inspiring and innovative teaching cases for intersection line in descriptive geometry.
