Fusion fails to create a flat pattern for a relatively straightforward part

Anonymous — Tue, 31 Dec 2019 22:26:49 GMT

Very simple part - flange a rectangle, flange one of its edges at an angle, then flange two of the side edges.

Fusion fails to create a flat pattern for this shape.

Warning: FlatPattern1
Compute Failed
Can't successfully process relief geometry. Check the body and parameters, then try again.SM_UNFOLDER_REPLACEMENT_WARNING.

How do I work around this? It looks like a bug in Fusion 360 to me.

Side note: Fusion's errors seem quite useless without a geometry object attached to them.

Your 10 deg kink fold does not have enough room for your choice of relief.

Overide it in edgeflange 3 to 'no replacement' and you should have no problems

In the repro file I attached to this question, the solution doesn't fix the flat pattern, but it changes the error to some unspecified "internal" error.

In my actual design it did fix the issue

What did you have to do to fix the issue?
