malcolmstroudThu Oct 25, 2012 6:58 pmTrying to show a total for the length of a particular wall type, the lengths are showing but the 'Calculate Totals' box is greyed out. I can total Materials:Areas and Materials:Volume, but I want the wall lengths to total. Any ideas? I am in Revit 2013.

You may want to post your issue to the Autodesk Discussion Forums where the user community and Product Support Team work together to answer users’ questions. There you can also add screen shots and post the file itself so the problem is easier to communicate.
