Is there a way to un-blend an edge? For example, after getting close to a final model, all edges blended (generally 'constant blends, radial') if you want to make major changes and have to rebuild a region, it would be helpful to be able to undo a few blended edges.

The alternative I see is to go back to an earlier model version (or backup) and start over some ways back in the design.

Anyone have tricks to solve this?

If the history tree doesn't allow it, or if a solid is imported from externally, the criteria is generally that defeaturing can be done relatively simply when the feature is built on primitive faces: planar, cylindrical, spherical or conic. Otherwise, you generally have to rebuild the faces involved.

Wow,

Thanks much. Guess I'll go back and read the manual again...
