An interesting bug of the standard function ;)

[Anonymous]

Hello! 

In my code I use Revit api function "Distance". Like this:

C.Distance(p)

I got an interesting error. If C - is arc and p - is center of this arc, this function doesn't work.

I got error:

Distancethrew an exception of type 'Autodesk.Revit.Exceptions.InvalidOperationException' Double {Autodesk.Revit.Exceptions.InvalidOperationException}

Would be the same limitations as described within Curve.Project method exceptions I assume (generic solutions).
