Using xView

1. Select the geometry to check; typically an Edit/Editable Mesh/Poly object. There is no need to access a sub-object level.
2. Choose the type of test to perform from the xView menu. By default, you can find this menu on the General viewport label menu (the "[+]" viewport label menu) and the Views menu (Default menu system).

   The test is performed immediately and the results, if any, display in the viewports as green-highlighted sub-objects: vertices, edges, or faces. At the same time, the name of the test and its numerical results display at the bottom or top of the viewport.

   Note: If any of the flagged sub-objects are already selected, they remain selected and display normally at the relevant sub-object level. Thus they are not highlighted in green when the relevant sub-object level is active. However, they’re still flagged and, if you deselect the sub-objects, retain the green highlighting.
   
3. To convert the highlighted sub-objects to a sub-object selection, reopen the xView menu and choose Select Results. To use the selection, access the relevant sub-object level.
