Sketch coordinates off, can they be reset?

[mcramblet]

I'm working with an imported file coming from Rhino, which I've defeatured and am rebuilding in Fusion. The model has been acting a little odd, but here is a problem that's causing me some fits. The sketch coordinates of some of the surfaces is off. In the Screencast, I want to sketch on the surface in the middle, the model is centered within Fusion, but when I try to sketch on the surface, the sketch coordinates are at some odd angle. I'm pretty sure this is due to the questionable build of the imported Rhino file, but is there any way I can "reset" the coordinates on a surface, when this happens?

The sketch origin is usually projected into the sketch plane from the origin. Are you seeing this behavior or something else? There is no method to reset the datum for the sketch plane that I'm aware of.

Could you work around by manually creating some reference sketch geometry and "fix" the sketch entities so that they act like a "faux" origin?

Instead of using vertical/horizontal constraints, use parallel and perpendicular constraints.

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

My improvised work-around was to create an offset workplane from the orgin, to the surface that I wanted to sketch on. I was able to do what I needed, I just haven't seen this type of behavior, the sketch orgin is not being projected from the orgin, at least on this surface of this model.

Something is certainly goofy with this model, there has been other oddities with it. I guess I might just calk it up to a bad file being imported as a starting point.
