In the Repouss© dialog you can manipulate the constraint (sub-path) using any of the Internal Constraints tools to either punch it out to make a hole or add separate extrusion parameters. You can also add constraints to an existing Repouss© object by drawing a selection or path and choosing either 3D>Repouss©>Create Constraints From Selection(s) or Selected Path(s). You can also use the Add(Selection) or Add(Path) buttons in the Internal Constraints section of the Repouss© dialog.
