The only way to sacle an object proportionally (aka furniture) in Dialux today is in the 3D view. This makes it impossible to scale accurately with a reference point. Is there a way to scale by dragging a scale handle that would affect all three axis of the object but in any 2D view?

I need to scale the object without deformation but using a 2D view to make it accurate.

The 3D view won't snap to where I want and also I need to have be zoomed out to pick up the handle making it very difficult to be precise.
