Chapter 10
Using Equations

Parametric sketch relations are not the only way to drive dimensions with intelligence. You can also use equations and variables. Equations help you create simple or complex mathematical relationships between dimensions. Global variables can be used in equations just as other dimension names can.

IN THIS CHAPTER, YOU WILL LEARN TO:

• Use equations to create relationships between dimensions
• Link dimensions together
• Assign global variables
• Enter expressions
• Control suppression states of features and components
• Link to an existing equation from a SolidWorks model

Understanding Equations

You can gain access to the Equations dialog box by using the Tools toolbar or by choosing Tools ➢ Equations from the menu. Equations are stored in a folder at the top of the FeatureManager. Figure 10.1 shows the Equations interface.
