So, I’ve got a simple shape, a hollow rectangular prism, i.e. a 3D rectangle , but only 4 walls top,bottom, right and left,a d you can look though from front to back. I need the length to increase by 28mm. One way is I can click on left outside wall and pull 28mm, then select left inner wall and push 28mm.
Is there away I can do this in one simpler step?
