Just checked-out Manipulator WB for first time; NICE!
Very nice AdHoc/On-The-Fly (displayed) dimensioning that was missing from WFeatWB.
Do you have any aspirations to achieve this type(shown below) of object MANIPULATION? This is one of FreeCADs missing links IMO!
People have been begging for this type of tool as long as I have been on the forum; and I am sure for longer then that.
Ever since Apple and Microsoft "BORROWED" this UI style/technique from XEROX PARC, It seems every other CAD-like App (heeks, rhino, autocad.......), Drawing(MacWord, msWord........), illustration (Adobe, Inkscape, LibreDraw.........), Wordprocessing, etc. tool has had THEM forever......but not FreeCAD.
If you could do this, I would certainly nomimate you as Emperor of FreeCAD!
