Abstract
IGES/PDES is an internationally accepted standard protocol for transferring the information of a two-dimensional or three-dimensional model between different CAD/CAM software. Any solid model can be constituted by a number of surfaces. Trimmed surface is one of the most important entities used to design a two-dimensional or three-dimensional model in IGES/PDES. The main idea in this article is to extract trimmed surface entity information from an IGES protocol created in a CAD/CAM software. Then, from the extracted information of trimmed surface entity in the model space and in the u– v space, a new u– v space is developed for meshing. After meshing the geometric region in the new u– v space, the meshed geometric region is transformed back to the model space by using a particular transformation. A Fortran code which can be used for pre-processing in Boundary Element Method has been developed by the present authors. Some meshed surface models are presented in this paper as examples.
