SketchUp Procedures use Procedural Tools to create or edit geometry as non-destructive Procedural Components.
You can edit, nest, and reuse components created with Procedural Tools like other SketchUp components. Make changes to the original drawing or adjust the component in Entity Info.
To access Procedures, select Procedures in the Menu or enable the Procedural Tools toolbar from View > Toolbars. You can dock the Procedural Tools toolbar like any other SketchUp toolbar.
