To Delete a Workspace
You cannot delete workspaces in the Creo browser.
You cannot delete the active workspace or a workspace that contains checked-out objects.
Before you delete a workspace, you must check in the objects or cancel the checkout of objects to the workspace.
1. Click Site > Workspaces on the Windchill toolbar. A table lists your workspaces.
2. Select a workspace and click Delete in the table header.
