• Avoid using the third option, unless you need
to repeat a 3ds Max version 1 attachment for
compatibility with a previous project.

you have an unassigned sub-mater ia l that you

vertices, edges, and faces. You can slice an editable

is available at every sub-object level except the
Vertex sub-object level.

To crea t e a new fa ce us i ng Cut:
1.
Convert the geometry to an editable mesh.
2. OntheModifypanel,choosethe

3. On the S election rollout, turn on Ignore

4. On the E dit G e ometry rollout, in the Cut and
Slicegroup,clicktheCutbutton.
5. Click the first edge you want to subdivide, and
then move your cursor toward the second edge.

current cursor location.
6. Click the second edge. This edge can be
anywhere, cutting across as many faces as you
like. A new visible edge appears.
7. At this point, a new dotted line is connected
to the mouse cursor, originating from the last
point you clicked.

To start or end a cut at a vertex, set snap to
