Mounting boss not following reference

Question asked by Jeffrey Accursi on Jun 17, 2014

Hi all,

I'm creating a part that uses several mounting boss features. I don't have much experiecne with these. They are all driven by a sketch defining the centerlines (2D sketch of several circiles) and various 3D surfaces for location. All use the FRONT plane for direcition.

Here's the problem: Whenever I make a change to the model, the bosses decide to move around on their own. Editing each boss causes it to snap back to the sketched circle reference. This is extremely frustrating.

Notice in the pictures the reference sktch is highlighted, but the boss is no longer aligned to it. Then, once editing the boss, it magically snaps back; no other input is needed.


Anyone seen this issue?


edit: what seems to be happening is when the reference sketch moves, the bosses are not moving with it.
