Changing and Checking Geometric Constraints

Changing geometric constraints



Constraints defined in the previous example contain parametric values. Here, new values are selected.


The solid was rebuilt after changes of parameters. The pitch between the grooves at the bottom is defined by geometric constraint. After the change, the pitch is different. The pitch between the holes remains constant. Moreover, both holes are constrained as one group. If you need to fix both holes at the grooves below individually, the hole at the right side needs to be removed from the constrained group. Then, define its constraints separately.

Definition of constraints for the second hole


A constraint at a distance from the patch was selected. Because the detected patch belongs to an object constrained in a different order, the selection is blocked automatically. If a constraint was performed, such a solid would not be rebuilt properly.


You may display a scheme of constrained links. The scheme highlights links between objects. Blocked selections are more obvious, if you click an object in the list. You can see an anchored object as well as an object the selected one is anchored at. Obviously, you cannot anchor an object A to an object B if the object B is already anchored to the object A (directly or via a chain of multiple constraints).
