I wrote about a problem with Transformation tool in this thread (losing the control of manipulation) but with not much attention...
https://forum.freecadweb.org/viewtopic. ... 30#p221937
I prefer to write more findings about this topic in this thread instead.
The thing is I found that this problem is more related with the Draft Grid tool, apparently.
When the Draft Grid is ON, the Transformation tool cannot be rotated in X,Y,Z axes. Please see the video:
I don't know if this a bug or the Grid is a limitation of Transf Tooll (including z-axis rotation).
