Some specific procedures of geometrical modelling in the PrESMod language for 2D parameter geometric modelling

摘要

The PrESMod modelling language uses lines/commands for the description of entities and modifications such that characteristic points, coordinates of characteristic points and other geometric parameters, relational position expressions, functional entity descriptions and also three types of relational statements for selecting one of two possible point sets can be used in the geometric description. In this work solutions have been analysed for problems of geometric modelling when based on one part of the modelling procedure, after specifying characteristic points, coordinates of characteristic points, characteristic geometric parameters, such as diameter, radius, angle, length and also parallel, normal, tangent relations, there are several solutions for the given entity (how to obtain one solution from two or more solutions). Finally, two commands in the PrESMod language for 2D parameter geometric modelling are given.
