Abstract
Modelling in CAD-applications demands a mapping of the structure of the geometric objects and a description of the relation between them. In purely algebraic modelling there are equations between the elements of the geometric model defined, which are solved to find the characteristic points of the model[SeGo87]. Another way is to use geometric reasoning mechanism in which the dimensions and geometric relationships are defined as either facts or rules [RSV89,VSR92]. To model the relations constraint systems are well suited. In this paper we describe two methods.
