I have a number of sweeps in my model and I want to get the length of them and put it in to another parameter, the bit I’m finding hard to get my head around is the bit you have done so thank you… would you be willing to share the .Dyn or the python script please?
You don’t need python if your trying to get sweep length from your revit model. My example above is only for family Editor. For project you can try as shown below example for duct fittings elements. Formula to get sweep length is {2Math.PICenterRadius/(360/Angle)}
