Summary0003589: Fully constrained Sketch becomes overconstrained on deletion of an element
DescriptionPlease have a look at this fully constrained model from a forum post. There is construction line marked and if I delete it, the Sketch becomes overconstrained. In the subsequent post I have removed one by one further elements until there were only two left. One of the angle constraints seems to point to nowhere.
This might be related to issue 3529

It might be the same situation as in forum post.

The radial construction line has an angle constraint. Deleting the radial construction line does not delete the angle constraint.

Simple test: Draw two lines with the polyline tool. The connection point should be coincident with the sketch origin. Constrain the two lines with an angle. Now delete one line. The angle constraint is not deleted, but constrains to an axis now.

Exactly Ulrich!

Angle constraints shall not be transfered, as it is only very exceptionally that it is possible at all.
