Frequent question: How do I link a global variable in Solidworks?

How do global variables work in Solidworks?

Global variables in SOLIDWORKS are user-defined names that are assigned numeric values. These can be used directly in a dimension or used in an equation. They make it easier to understand and modify equations. For example, in the image below, we want the bottom line to always be twice the thickness of the top portion.

How do you link dimensions to global variables?

Double click the dimension, then in the Modify dialog box, type = (equal sign) and several characters of the global variable name. A flyout menu appears with a name that matches the characters you have typed. Both dimensions become linked to the global variable. Repeat for as many dimensions as needed.
