Discrepancy between .19.2 and .20
Can't create an AditivePipe with a sketch with multiple close shape.
The path look like that:
and generate that in 19.2
In 0.20, it returns "Broken Face".
If a file is imported from .19.2, the additivepipe seems to work. However, a do a pocket as a next operation, and it said, Result as multiple solids.

Re: Part Design Additive Part problem in 0.20
You cannot Pad a sketch with T-junction (or with adjacent forms).
You need to transform inside line to construction mode (blue) to draw just a big rectangle.
Imho, FC 19.2 cannot/should not Pad/Pipe this.

Re: Part Design Additive Part problem in 0.20
I did attach 2 demo files to my original post. One created by 0.19.2 and the others by 0.20
It is working quite well in .19.2. But not at all in .20
In fact, if I create the sketch in 0.20 and save them. Re-open them in 0.19.2, it does not work and return
22:39:29 <Exception> TopoDS::Face

Re: Part Design Additive Part problem in 0.20
I agree with @shalmeneser. Your sketch is faulty. 0.19 shouldn't have allowed you to use it.
It may look like regression, but when you're working 'out of spec' you can expect such things actually to happen.
Re: Part Design Additive Part problem in 0.20
IIRC there were improvements made in recognizing faulty sketches with revolves, and I'm glad to see they work on sweeps too. Such models led in the past often to problems in later steps, where they were much harder to detect.
