What do you mean by that? Do you want to generate the models with python? Then you may consider modeling them in a more stable way not relying on edges or vertices, e.g. by starting with a sketch which contains the fillet itself.

I'm afraid a bug report won't help, "Invalid tolerance value" comes usually from the third party OCC kernel.

Re: help on sheet metal script
Hi,
you can unfold your "Error-unfold-sheet-metal-with-part-fillet.FCStd" file, if you use i.e. Defeaturing WB tool and unfold the result.
Here the unfolded file, where your last fillet is conserved ... -
Regarding your last file, where last fillet is on the border of the shape, I don't see why you need to add this last fillet before unfolding...

Re: help on sheet metal script
No, I wan't not to generate models with python (BTW I have no skills about that), I would like to share a tutorial about sheet metal, but not about native FC model or cartesian models. I mean about imported step parts or part with complex geometry (far from cartesian shape).
This kind: https://forum.freecadweb.org/viewtopic.php?f=24&t=34593
In order to prepare such kind of part for unfolding I have my workflow. The end of this workflow concerns peripheral fillets. Of course I could stop the workflow to the previous step, namely the offset feature. But that would be pity. If I do this peripheral fillets should be added on the unfold sketch, IMHO it is not convenient.
(This limitation about peripheral fillets does not occure with traditional sheetmetal workflow, I mean by using sheetmetal WB features)

Re: help on sheet metal script
Fillets should be modeled as late as possible, this holds for other CAD programs as well, e.g. https://community.plm.automation.siemen ... ba-p/25914. You should consider this when creating a tutorial.

Re: help on sheet metal script
Sure, but the peripheral fillets I'm talking about are the last features, so what the mater?
Or you mean about bend fillets on the extruded shell feature in my part? Well if it's about that I can't do in an other way, it's too convenient to use it in my workflow.
Re: help on sheet metal script
In the model you have uploaded the fillets are applied to the face and not to the extruded solid. So the extrude comes after the fillet, which means the fillet is not the last feature.

Re: help on sheet metal script
Yes you are right, so you are talking about "bend's fillets". I have to process this way otherwise the workflow I'm talking about doesn't exist anymore...
However, remember I have no any directly related troubles about the fillets of bends, troubles seem due to very last peripheral fillets only.

Editing previous post is getting very difficult to follow the thread workflow, because your editing is making previous replies out of the contest...
Moreover you missed to read my previous reply in which I also uploaded the unfolded file "Error-unfold-sheet-metal-with-part-fillet-unfolded.FCStd":

And here your latest file unfolded
Re: help on sheet metal script
Copy that
I have read it, ok it's a way to avoid the problem and to get unfolded part, but it adds one step in addition. If no choice I will do in this way, thanks.
