Abstrakt v dalším jazyce:	The paper presents the internal graph-constructive representation of parametrised geometry in a CAD system that supports the design of objects with variable topology. A constructive constraint solver is extended by adding two implicit constraints: ed (equal distance) and ea (equal angle). The necessity of supporting both constraints in a model with structural parameters is argumented. The basic solvable patterns involving these constraints and the forming and merging of circularly linked clusters is presented. The applicability of the constraint solving to hierarchically structured parametric objects is also shown with a practical example.
