Methods for generating mesh surfaces using cad systems

Abstract

One of the most popular graphic software in CAD systems is AutoCAD that is used frequently by a very great number of users thanks to its numerous advantages. In this paper we present several methods to create mesh surfaces which consist of polygonal network generated by the 3DMESH and PFACE commands. Among other representative commands for creating mesh we can mention: 3DFACE, EDGESURF, RULESURF, TABSURF, etc. The SURFTAB1 and SURFTAB2 system variables which determine the network density onm the M and N directions have also been highlighted.
