Expanding plane size while keeping existing vertices This is a workflow question. What is the fastest way to get the plane on the right starting with the plane on the left? I think in 3ds max you can select the vertex I have selected in the picture and "drag" out the plane, creating a plane inside a plane. Can you do this in blender? I know you can start with a larger plane and inset (I) but there must be a more efficient way.
Here's an alternate method that might be useful in some circumstances. In edit mode, select one of the vertices of the plane, and from the context menu of the snap tool (SHFT - S), select "Cursor to selected". Next, invert the selection (CTRL - I), to deselect the original vertex, and select the other three. Then set the pivot point to 3D cursor, extrude the selected vertices, and scale to the desired size.
