A selected (highlighted) individual object or group of objects can be removed from the model by invoking the "Delete Objects" menu command, from the Edit menu. Note: A link cannot exist without both end-nodes; thus when one end-node is removed, the link is also deleted. To delete a vertex from a polylink, hold down the <Shift> and <Ctrl> keys and click on the vertex to be deleted.
To delete a background picture:
- Click the Background Image Properties tool from the Background Images Toolbar.
- Select the background image you wish to delete.
- Click the "Delete" button. Invoking the delete background tool at this point will immediately delete the background.
- Click "OK" to close the window.
