Geometric Accuracy Example
The following example is provided to give additional background on the nature of the problems encountered in the representation and exchange of Boundary Representation (B-rep) solid models.
Figure 1 shows an “idealized” solid model. Vertex A “is” the intersection of edge curves e1, e4, and e5 and edge curve e1 “is” the intersection of face surfaces F1 and F2.
