Many SolidWorks Users use the link to thickness option for extrusions and cuts in a sheet metal part but may not realize that you can activate this option without having any sheet metal features in your model. Link to thickness is an option that can be widely used in many other model types, not just sheet metal. Activating the option is as easy as 1, 2, 3.
1. Right-click on a model dimension you would like to designate as the thickness.
2. Select Link Values from the pop-up menu.
3. Enter the name "Thickness".
The Link To Thickness option is now available in any extrusions you create or edit.
