I created a family in Revit 2011, Dimensional lumber that does not auto-join like the default family, and added a length attribute. But in the schedule I would like for the length to round up to the nearest 2 foot so a 4'-5 1/2" rounds to 6' and so on I cannot figure it out. I am just testing Revit to see if it is a fit for my company, so I am no expert, does anyone have an advice?
