I'm having trouble unfolding a very simple sheet metal part.
Context: it is a stair tread for a curved stairway.
The feature Surface-Offset1 is taken from the assembly in which the Tread part exists. Then I use the Split function wth the Surface-Offset1 to trim the ends off so that the tread mates perfectly with the sides of the stairway which are curved.
Here's the problem ... I try to place a Flat Pattern view into a drawing, and it fails, ie the view shows me the folded part.
If I click the Flatten menubar button, I also get an error on the Flat-Pattern feature. When I click What's Wrong? I get "The bend may be fused with other bend" . (Is that even a cromulant sentence?)
When I suppress the Split feature, it folds fine.
