Let's say I have three identical meshes, but some of them are rotated as shown in the image:
Now in edit mode, I want to move the face to change the size of the mesh, what are possible workflows for the mesh to resize? See the arrows I drew in the image. I want the face of the mesh move relative to its object. I tried experimenting with parenting object, shift+G (select face by normal/coplanar) etc.
I am stuck. Hope I explained myself clear.
