Creating Subdivision Models

Subdivision modeling allows for the easy, intuitive creation of free-form shapes, whether to design an object or explore a concept. A subdivision primitive object is created using the Create Subdivision Primitive command. The object is then sculpted using a combination of the Edit Subdivision tool’s modes.

To create a subdivision primitive object:

1. Select Model > Create Subdivision Primitive.

The Create Subdivision Primitive dialog box opens.

Alternatively, double-click the Edit Subdivision tool to open the Create Subdivision Primitive dialog box.

Click to show/hide the parameters.

Parameter	Description
Subdivision Primitives	Select the object’s shape; the object preview adjusts to show the shape selected
Size	For all shapes except torus and ring, enter the size
Major Radius	For the torus and ring shapes, enter the major radius
Minor Radius	For the torus and ring shapes, enter the minor radius
Segments on Major Axis	For the torus and ring shapes, enter the number of segments on the major axis; the number must be greater than 2
Segments on Minor Axis	For the torus shape, enter the number of segments on the minor axis; the number must be greater than 2
Center Location	If Center at Next Click is not selected, enter the X, Y, and Z coordinates to place the object
Center at Next Click	Select to center the subdivision primitive object on the next mouse click in the drawing

2. Set the parameters and click OK. If Center at Next Click is selected, click in the drawing to place the object.

The subdivision primitive object is ready to be edited, using the Edit Subdivision tool.

Most tools and commands that can be used to edit solid objects can be used to modify subdivision objects. However, the following tools do not edit subdivision objects:
