To Define Slivers Using the Define Slivers Tool
1. Click Structure > Gaps/Slivers > Define Sliver. The Define Slivers dialog box opens. SLIVER0001 is displayed on the left of the dialog box and the primary collector, Surfaces, becomes active.
2. Select a surface that contains slivers. The selected surface is added to the Surfaces collector and the edges that correspond to the sliver are automatically added to the Side 1 and Side 2 collectors of the Define Slivers dialog box.
 
To select more than one surface, hold down the CTRL key and select the surfaces in the graphics window.
In some cases, it may be necessary to manually select the edges representing the sides of the sliver. You may also edit the sides that are automatically selected.
3. To add a new sliver, click New Sliver in the Define Slivers dialog box and select the sliver surface in the graphics window. You can also right-click in the graphics window and click New Sliver on the shortcut menu to create a new sliver.
4. To remove a sliver surface, select the surface in the Surface collector, right-click, and click Remove on the shortcut menu.
5. Click Add to Wireframe to add the new gap to the wireframe.
6. Click OK on the Define Slivers dialog box.
