Here's a great little set of REVIT families for Stepped Footings.
Surprisingly enough REVIT comes with NO 'out of the box' method to properly model a stepped footing and it's a major "Pain in the A$$" to try to model one. As a newbie it's next to impossible.
Well . . . .fear not my fellow reviteers . . . you can download the 3 and 4 stepped footing families shown above in the ZIP file below.
Any problems with it just drop me a line : )
