creating a new PolyCurve()

So here is a little hang up that I have been experiencing:

I getting an "invalid Curve" when doing this:

def toRHPolyCurve(self):
rhPolyCurve = rc.Geometry.PolyCurve()
for j in self.curves:
if type(j) == MSLine:
rhPolyCurve.Append(j.toRHLineCurve())
elif type(j) == MSArc:
rhPolyCurve.Append(j.toRHArc())
elif type(j) == MSNurbsCurve:
rhPolyCurve.Append(j.toRHNurbsCurve())
return rhPolyCurve

This is a definition that returns a PolyCurve() yet Grasshopper tells me its an invalid curve. Ideas?

You can use the Polycurve.IsValidWithLog method to see why Rhino might think the curve is invalid.

Now, I got it to where it returns a Curve object, but its not valid to use inside of Grasshopper.

You can use the Curve.IsValidWithLog method to see why Rhino might think the curve is invalid. I can't tell just by looking from all the way over here.

Yes, IsValidWithLog is pretty good. I think I know what my issue is now. Thanks!
