Subdivision modeling in Alias starts with the Subdivision Workspace. There, models can be initiated from primitive shapes, with control points added that allow you to modify and refine the design. Curves are instrumental in extruding, sweeping, or revolving subdivisions to form the initial design, while the Retopo toolset is used to build subdivision topology on meshes, NURBS surfaces, or flat View Planes.

For the finer details of your model, you can use tools such as Extrude, Insert, and Bridge on faces and edges. Additionally, tools like Bevel, Crease, Cut, Weld, and Extract enhance topology flow, while symmetry, Pick tools, and display management options streamline the modeling process, ensuring efficient and precise design adjustments.

At the end of this module, you will be able to:

Identify the essentials of subdivision modeling in Alias, starting with fundamental terminology and workspace customization.
Create and refine models using primitive shapes, control points, and various subdivision tools like Extrude, Insert, Bridge, Bevel, and Crease.
Work with the Retopo toolset, symmetry, and the NURBS modeling tools.
Optimize your workflow through display management, hotkeys, and the Trim a Untrim tools.

Video quiz

When you need to extrude multiple edges along a curve, such as a wheel arch, why it is best practice to use the following workflow: pick the object, turn on controls display, pick the edge loop, and then use the Extrude tool?
