FreeCAD
I mean, sheet metal WB features are really cool for pretty cartesian parts (more or less cartesian), i.e. boxes, sheet metal casing, etc...
Very convenient features and parametric furthermore: thanks to sheetmetal WB devellopers!
However, those feature are cumulative, I mean it is a way to modelise by serial features. That is no so easy to modelise a full 3D parametric model in this way, easy to modify by overall dimensions for eg.
So, the workflow by using offset feature from faces of 3D model allows to get quicly full parametric and full 3D sheetmetal parts.
The tiny problem I face with concerns only peripheral fillets, that's not so serious problem, but I would like to be able to complete the workflow without any bug in order to get a smouth unfold sketch, with all peripheral fillets on it.
If it's not possible to solve the error about "compound shell invalid tolerance value" from Part->fillet feature, then I will do as Maurice told me: https://forum.freecadweb.org/viewtopic. ... 90#p303828
Am I clear? I reach the limits of my skills in english sorry.
In this way I will share a tutorial to talk about:
- the native sheetmetal WB features: very convenient for most of sheet metal parts
- the alternative workflow I'm talking about here for full 3D parts (parametric or from 3D step file)
Please find below an additional picture of an exemple. For such kind of full 3D shaped part, the workflow I'm using (from faces with 3D offset) is more convenient compare with sheet metal WB features.

Such kind of tutorial should give various ways to users to get sheetmetal sub-parts from any 3D solid, and very well fitted (for MIG welding seams I mean)
