Thomas, No, i went over the syntax extensively. The syntax is RS.AddCurve(points, degree), so 3 represents the degree of a bezier curve. I'm doing fine with all types of functions which use 2 x,y,z coords, but all arrays -tuple of tuples- fail. The odd thing is that when i use RS.GetPoints() which is a method to get back user-defines x,y,z points, i get a tuple of tuples containing these points. Though when i write these back to the program, all fails:
I admit posting this problem also to the more specific python-win32 group, though no response there yet... >>>s = RS.GetPoints() >>>s ((-7.0, -30.0, 0.0), (15.0, -24.0, 0.0), (-7.0, 12.0, 0.0), (14.0, 29.0, 0.0), (28.0, 10.0, 0.0), (20.0, 1.0, 0.0)) Cool, I get to choose points in the GUI, right back into python, wicked! Though when I send these points back to the app: RS.AddPolyline(s) The same error all over again: --- Traceback (most recent call last): File "<input> ", line 1, in ?
