PartDesign: Fillet and Subtractive Pipe are failing to make a fillet.

[leoheck]

Is there an existing issue for this?

Problem description

I have this simple but irregular shape that I am failing to add a fillet. File: test_Body_top_fillet.FCStd.zip

Side view

Front view

I want to make a fillet around this highlight edge..

The fillet tool is not working, no matter the radius of the fillet.

The Subtractive Pipe tool with something like this is also failing.

It is doing something, but not the right thing, see.

I don't even have the "Allow multiple solidis" enabled in the settings.

To make it simpler, I am not even using a complicated path for the pipe tool I am using this flat square with rounded corners.

Is it a bug? Is there any workaround that I can use to make this filet?

I also tried this by selecting the edges to create a sub-shape binder. The pipe tool proposes something that I would like to have. But the resulting object is not ok.

[leoheck]

The Additive Pipe fails to add mass in a different way.

[leoheck]

Ah, changing the profile I could see the issue. The path is not closed. Is it right?

[leoheck]

Ah, it works if I remove a section of the path.

The bottom_left corner

Ok, I can make 2 paths to make this work.

Now I understand what it means when it says profile is overlapping. To close the path, it has to overlap a bit... This would not be a problem if it could work like the Pattern Tools I guess.

[leoheck]

Awesome, seems good enough.

[leoheck]

Ok, so question. Is this a bug, or should I close this. I would like to see this working with a single path, if possible.

The file seems to be an issue, on opening and recompute I ge ta ton of errors without changing anything:

[leoheck]

Why don't I get these things? Unless this widget (which I don't use because it is way annoying), don't report the same things as the Report View.

[leoheck]

The Sketch492, for instance, is a simple, fully constrained sketch that does not give me any issue when analyzed. Which version are you using @maxwxyz ?

[leoheck]

When I bring this solution to my project. It does not behave like when it was in a reduced form on a different file. Features look like they will be ok, but the mass is not removed.

Features started to remain active together without being edited. FreeCAD has been open since yesterday, it may be related, or not.

[leoheck]

Hm, it works. I just have to make things (I am doing this with all the features before of the current one) to be recomputed, and then recompute. I am also using "Skip Recomputes" since the project is big.

[leoheck]

Now, 3 features are active at the same time.

[leoheck]

I don't even have a lack of resources.

I don't have recompute errors with this file. But it seems to be still relevant. I can't fillet that outer edge.
