How do I sketch on face of sheet metal model?

Kyler_Walker

When I create a sketch on sheet metal, I try to select the face of the part as the sketch plane, but a face of a previous feature, usually a hole, gets selected.  This is annoying because I lose subsequent sketch planes when I edit features.  I end up having to sketch on one of the coordinate system planes to make my sketches resilient.

Please share a link to your model and we will see if there is a way to make the sketch face selection stable. Without a specific model, it is hard to tell why the face reference would change.

In general, drawing on sheet metal takes the following steps:

• Make sure you roll back to before the Finish sheet metal model feature.
• Open the Sheet metal flat view panel.
• Select a face from within the flat view as your drawing plane.

That is my general approach, except my sheet metal usually has planar faces, so I don't usually sketch on the flat pattern.

When I get a chance, I will try to make a similar part in a new document that I can share.  This is currently happening on a part made with 64 features, including many in context references.
