Research on architectural CAD-aided design based on computer 3D reconstruction technology

The traditional building 3D modeling method is time-consuming and labor-intensive, and the accuracy is low. This paper adopts a new type of computer 3D reconstruction technology, which is based on the rapid assembly design method of 3D embedded parts based on generalized parametric templates. Through a large number of feature points and linear data of a large number of buildings, a general parametric template of embedded parts can be established, including various information such as 3D parametric shape structure, installation and positioning method, and 2D projection sketch, so as to quickly carry out architectural CAD assistance Design rebuild work. The method in this paper has been integrated into the 3D CAD software Inters for commercial and industrial building structures and has been applied to practical engineering design.
