Thought I was doing something unholy as usual, but instead found a bizarre #gh3d bug. Try it: Run an empty item into a Curve parameter input, and it converts into the first crv in the RhinoDoc! GH 1.0.0007. Real monkey wrench if you’re not paying attention…
Oh, by the way, it works with Breps as well – probably with any geometry type? These seems to be a generic casting error.
