Lesson 4 – Modeling the Wheel
Using the Revolve
Command
4.1 Lesson Objectives
After completing this Lesson, you will be able to:
Explain and use the Revolve command.
Explain and use the command Convert Entities.
Explain and use the Centerline command.
Explain why the Wheel Sub-assembly was not created as a single part.
Create part models using more than one PSDF.4.2 Introduction
The Revolve Boss/Base command, like the Extruded Boss/Base command in Lesson 3 can
be used to create 3D solids from 2D sketches. Both commands belong in the Features toolbar.
Revolve creates solids by rotating the 2D sketch around an axis of revolution.
4.3 Modeling the Wheel
The wheels and tires should be two different parts because they are different materials and are
made using completely different manufacturing processes. Skateboard wheels can be injection
molded using a hard grade of urethane, a type of synthetic rubber. Skateboard wheels can also
be made from steel. The tires are made with a softer urethane. The assembly is made by
placing the wheel in a mold and pouring urethane around it.
To create a model of the wheel, we will follow the five steps we learned at the beginning of
Lesson 3:
1) select a plane,
2 ) sketch,
3) add dimensions,
4) use the Revolve command in the Features toolbar and, finally,
5) document the design information and references.Remember PSDF: Plane, Sketch, Dimension, Feature.
