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 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).

■ Modify some adjacent faces without triangulation. When you move, rotate,

or scale a vertex and press and release Ctrl once, some adjacent planar

faces might be adjusted.

If you press and release Ctrl a second time, the modification returns to the

first option, as if you had not pressed Ctrl.

Delete a Vertex

You can delete a vertex that connects two parallel edges that are collinear and

do not intersect on any other edges.
