Problem Description

Sometimes a model will include a wall of zero length that cannot be deleted. This might be a sign of a model corruption or some data that did not import correctly from ISM. The walls may cause errors in the framing tables or show as an error in the Integrity - Data Check indicating that the wall has a span of zero.

Solution

There are two possible ways to remove these walls.

1. Show wall numbers on screen to help locate the wall, usually at (0,0). Use the Layout - Walls - Change Material command to make the wall Concrete, then use Layout - Wall - Delete Fence to delete it.   
2. If option 1 does not work, use Integrity - Align Walls and select the wall. In the dialog change one end coordinate using the lower right coordinates and then the Align button. After doing that a warning will appear indicating that the "Move results in wall having length (6 inches. Would you like to delete the wall?". Click yes to delete the wall.
