Beaver is a fast program for generating 3D model of I-beam, channel steel and other steel frames. Based on the existing 2D CAD drawings, he can automatically identify and match the relationship, size and specification between the installed parts and the installed parts according to the drawings, so as to realize the one key generation of 3D models. The whole program is divided into two parts, the first is the generator. Within this module, a preview of the steel part is generated outside the work area. The second is the installation device, which will install the components generated in the generator to the place specified in the drawing, and realize automatic data matching and connector generation.
