Lesson 3: Solid Object Modeling
3.5. Video Introduction to Solid-Object Modelers (Part 2)
Before continuing, let's recap:
- Solid-object modelers ("modelers") use one or more 3-D (X, Y, Z) coordinate systems to define and manipulate objects.
- Modelers can display objects in a number of ways, including 2-D projections, rotatable 3-D views, and wireframes.
- Basic manipulations of objects (or object components) include moving, rotating, and scaling. Using relative coordinates allows these operations to be performed on selected components relative to other components.
- Objects have properties and can be organized in hierarchies. The previous video showed how hierarchies can be used to group and move a car, its roof rack, and a suitcase. Extending that idea here, note that each of these objects has properties that can be either inherited or specified individually. If you want the color of your car and its roof rack to match, for example, you could specify that the rack's "color" property should be inherited from the car. If you later decide to change the color of the car, the rack color would be updated automatically.

Now watch Part 2 of the video tutorial, which explores how modelers use geometry and transformations to shape objects. There are five clips totaling about 24 minutes in length. Return here when you finish and click the Canvas Next button at the bottom of the screen.
Troubleshooting: If you are continuing directly on from Part 1, a Penn State–authenticated Lynda window should still be open in another browser tab. You can simply switch to that window and continue with Part 2. Otherwise, you'll need to reauthenticate and then access Part 2 with the second link.
