wedge with two vertices moved
You can modify the form of a 3D solid or surface by modifying one or more
vertices. Use grips and gizmos, or run the MOVE, ROTATE, or SCALE command.
When you scale or rotate vertices, you must select two or more vertices to see
a change in the object. Clicking and dragging a vertex stretches the 3D
object.
If you move, rotate, or scale one or more vertices on a 3D solid primitive, the
solid primitive history is removed. The solid is no longer a true primitive and
cannot be modified using grips and the Properties Inspector palette.
Vertex Modification Options
As you drag a vertex, press Ctrl to cycle through modification options.
Triangulate adjacent faces. When you move, rotate, or scale a vertex
without pressing Ctrl, some adjacent planar faces may be triangulated
(divided into two or more planar triangular faces).
