LineObject in Python

I need to define positions along a LineObject and get their relative position / parameter on the complete spline.

In C++, I can easily get those with CLine* LineObject::GetLineR(). In Python, there seem to exist neither the CLine struct nor the GetLineR method. So how can I achieve the same thing in Python? What is the LineObject good for in Python if I can't get any lines from it?

Thanks for any heads up,

Hi Frank,

LineObject.GetLineR() is missing in the Python API but there's another way to get line data in Python.

C++ API LineObject::GetLineR() just retrieves line tag data from an object.
The Python API provides the convenience function VariableTag.GetAllHighlevelData() to retrieve data from a tag. The function supports tangent, line, segment, normal, etc.

Note the line data is given as a list of dictionary with pos and t keys so the info from each CLine is returned.

Ah, that sounds useful, thanks!

I'll try that!

And it sure would be cool if that was mentioned in the Python SDK documentation 😉

Hi Frank,

I'll add a note to LineObject docs explaining how to retrieve the line data.
Note the solution is the same to obtain the segment data as well.
