[SOLVED] Sheet Metal: unfold doesn't work on version 0.19

[Giulio Buccini]

Hi all,

I opened some old files with my fresh updated version 0.19 and tried to get the unfold of a brackets, but I've got a message like "Unfold failed. Try to select another face."
After a moment of frustration, I have created again the bracket model from scratch with my latest version and tried to apply the "Unfold" operation again... Same result.

Just for sake of curiosity, I started the old 0.18, loaded the model and applied the unfold... and it works!
What's going on?
Any idea?

In the regular download page (https://www.freecadweb.org/downloads.php), below the Current stable version: 0.19.2 you can find Development versions : https://github.com/FreeCAD/FreeCAD-Bund ... kly-builds.
Just copy in the dedicated directory and give permission.

A lot of people don't see below the first screen.
