Conduit fitting length

Revit

Overall, this is a great solution. On paper there is …<10% difference in conduit length, but compared to real life situation this doesn’t affect anything.

sel = uidoc.Selection.GetElementIds()
sel = [doc.GetElement(x) for x in sel]

op = Options()
l = 0

for item in sel:
    try:
	    l += item.Location.Curve.Length
    except:
        c = [x for x in item.GetOriginalGeometry(op) 
            if isinstance(x, Arc) or isinstance(x, Line)]
        l += sum([x.Length for x in c])

#Assign output
OUT = l

This is the python code I use to find the combined length of a selection in Revit. It adds the length parameter of the conduit, along with the length of any lines and arcs in your conduit fitting.
Which, for the fittings I use is just the centerline, so the calculation comes out correct.

Hi @vlad.aleksandrovs for get the Arc Length of Fittings maybe try this:
Element.Geometry + Extract only Geometry Arc (with “isinstance”) + Curve.Length + Math.Round
Cheers
