Assigning global variables

Entering expressions

Control suppression states of features and components

Linking to an existing equation from a SolidWorks model

Parametric sketch relations are not the only way to drive dimensions with intelligence. You can also use equations, link values, and global variables. Equations help you create simple or complex mathematical relations between dimensions. Link values are essentially a quick way of making two dimensions equal. Global variables can be used in equations like other dimension names.

Understanding Equations

Using the Equations interface, you can suppress individual equations temporarily by deselecting the Active check box to the left of the equation. Equations can also be deactivated by a design table. I discuss design tables in more detail in Chapter 11, where I also discuss configurations.
