can't delete tangent constraint and apply to different geometry

[Noah_Katz]

I accidentally "missed" and applied tangent constraints to the wrong arcs.

I deleted and tried to apply to the right one, but get a solve error, as shown in the screencast.

This happens a lot as I fuss with this belt grinder design; I've taken to just deleting the lines and making new ones.

Solver bug?

I think you might be missing one small step. There are really two constraints to deal with here. One is a tangent constraint and one is a coincident constraint for the endpoint of the line.

Before applying the new tangent constraint:

1. Delete the old tangent constraint
2. Select the endpoint of the line
3. Select the Delete Coincident command from the right click menu
4. Then add the tangent constraint

I hope that  helps. Let me know if you have any questions.
