My construction includes a plate of 350 mm width, which I want to reduce to 150 mm.
So I selected the face, 'p' for pull, clicked the 'ruler' option, marked the opposing face and typed in 150.
BUT to my surprise, only the face is pulled, the plate remains its former size.
How is this even possible?
I thought I learned that a face is not an object on its own that can be moved separately.
What is the sense of 'extruding' a face when there is no volume attached to it?
