How to Access, Edit and Reshape a Polygon Proxy Object in Maya



Subdiv Surfaces are often defined by a much simpler polygon shape. As you modify the polygon shape, the organic shape of the Subdiv Surface follows.


Step One

Add a polygon cube to the workspace (Create > Polygon Primitives > Cube). In the cube options, set the Height Divisions to four and leave the Width and Depth divisions at one.

Step Two

With your object selected, click the Component Mode icon and click the Faces icon. Delete the top face, then select the Vertices icon.

Step Three

Using the Select, Move and Scale tools, reshape the object by moving and scaling groups and individual vertices.

Step Four

Return to the object mode by clicking the Object Mode icon. With the object selected, choose Modify > Convert > Polygons to Subdiv.

Step Five

With the Subdiv object selected, press the 1, 2 or 3 key to display the object with greater detail. This setting only affects the preview. The final rendering is not affected.

Step Six

With the object still selected choose Subdiv Surfaces > Polygon Proxy Mode in the Surfaces menu set . You can now return to the Component Mode and reshape the polygon frame.

Step Seven

To return to the Subdiv object without the polygon frame, choose Subdiv Surfaces > Standard Mode.

Polygon Modeling with Subdiv Surfaces

As you apply the various polygon modeling techniques to your basic polygon shape, the Subdiv object conforms to match the new object.

Polygon modeling techniques such as extrude, move faces, move points and delete faces can be quite helpful in creating your shape.

Simplifying the Polygon Proxy Mode Display

While working in the Polygon Proxy mode you may want to temporarily hide the Subdiv Surface.

To hide the Subdiv Surface, choose from a panel menu, Show > Subdiv Surfaces (deselect check mark). Just remember to turn it back on when you are finished editing or your Subdiv Surfaces vanish from that viewport.
