A constraint hierarchies approach to geometric constraints on sketches
We propose an approach that uses preferences on the constraints in order to deal with over-constrained geometric constraint problems. This approach employs constraint hierarchies,...

Well-constrained Completion and Decomposition for under-constrained Geometric Constraint Problems
In this paper, we consider the optimal well-constrained completion problem, that is, for an under-constrained geometric constraint problem, add automatically new constraints in suc...

A C-tree decomposition algorithm for 2D and 3D geometric constraint solving
In this paper, we propose a method which can be used to decompose a 2D or 3D constraint problem into a C-tree. With this decomposition, a geometric constraint problem can be reduc...
