Abstract

Existing modeling methods for modeling ladder like facilities are often limited to a single technical means and require a large amount of user input or guidance. To address the above issues, we propose a spline based parametric modeling method for modeling general complex ladder like facilities. Firstly, a facility framework spline generation method was improved to provide an editable initial framework. In addition, the method for calculating the position of contour points is improved, and the surface mesh of the facility is generated by combining contour curve constraint algorithms that meet various dimensions and geometric constraints that control the shape. Finally, a profile mesh generation algorithm was designed to achieve mesh generation of contour surfaces. The experimental results show that this method can be used to model different types of ladders like facilities. Compared with existing methods, facility framework spline generation and component surface mesh generation can significantly improve the efficiency of model generation.
