Abstract

In variational CAD design, parametric models may fail to regenerate raising the question of which parameter values lead to valid models. The problem is easy to state but difficult to solve. Using a simplification, we present an algorithm that computes for parametric models valid parameter ranges within which the model will regenerate. We explain also why the general problem is hard.
