Im in the middle of converting an old 2d casting drawing into 3d. I imported the dxf's for the top and bottom on seperate planes, and figured it would be easiest to just set up multiple other offset planes for the various features and converting the entities that I need from the original sketch as i go.. Not sure if that makes sense so ive included some screen grabs.
These are the 3 planes I have. I converted the original sketch on the top plane to both plane 2 and plane 5, deleting what i needed on that level as i go.
Here is the top level sketch that is giving me the error.
and the error itself.
Ill include the solidworks file so you can look at it. Its probably an easy solution and im just a rookie, but thanks for your help in advance.
