Modeling Subdivision Objects

EditSubd_tool.png 

The Edit Subdivision tool is in the 3D Modeling tool set.

The tool’s modes allow you to combine many different operations to sculpt a selected subdivision primitive object into almost any shape imaginable. When the Transform mode is selected, additional modes are available for manipulating the object.

Double-click the subdivision primitive object with the Selection tool to select the object and automatically activate the Edit Subdivision tool.

Mode
Description

Transform

Uses a 3D dragger to transform cage mesh faces, edges, and vertices in a variety of ways depending on the additional modes selected

Crease

Edits the sharpness of the cage mesh’s face, edge, or vertex to produce a smooth or sharp object

Face Extrude

Extrudes a cage mesh face, similar to the Push/Pull tool

Face Split

Splits a cage mesh face into five faces to create new cage mesh entities to edit

Face Hole

Creates a hole in a subdivision object’s face

Edge Extend

Extends an open edge of the subdivision object

Edge Split

Splits a cage mesh along an edge to create new cage mesh entities to edit

Translate and Rotate
(Transform mode only)

Uses the Translate and Rotate 3D dragger to manipulate cage mesh faces, edges, and vertices to reshape and rotate the selected object

Scale
(Transform mode only)

Uses the Scale 3D dragger to change the scale of the selected object or a designated part of the selected object

Re-position
(Transform mode only)

Repositions the 3D dragger without affecting the selected object

Align to Cage
(Transform mode only)

Keeps the 3D dragger aligned to the selected cage mesh entity

Align to Working Plane
(Transform mode only)

Keeps the 3D dragger aligned to the working plane (see Understanding the Working Plane)

After editing, the subdivision object can be converted to a generic solid or NURBS object; see Converting to Generic Solids and Converting to NURBS.
