I haven't tested your latest code yet, but I can see you are doing very interesting stuff there.

one DXF support, I need more understanding here. Using "Degree 2" seems to be risky to me.

Let's try to understand the group codes:

74 Number of fit points (if any)
11 Fit points (in WCS), one entry per fit point DXF: X value; APP: 3D point

reading/writing into DXF is now implemented. It stores the data as spline of degree 2. When reading, it reads the spline when degree is 2, even if the spline has been created by the original spline tool.
