VECTORSPLINE not well imported with LeadTools Vector

Attachment: ebl0861da.zip

Hello,

I am asking about the VECTORSPLINE structure which does not contain all the information necessary to build a nurbs curve. The definition given by VECTORSPLINE does not match that of DXF. For example it lacks :
- The degree of the spline curve
- The Knot vector values
....
For these reasons, I attach to this post a dxf file which contains spline entities and where LeadTools vector the dxf is misinterpreting the spline entities regarding AUTOCAD interpretation of the same file.

Please let me know if there are any raisons for that ?

Thanks

If you set the dwFlags members of VECTORSPLINE to VECTOR_SPLINE_CONTROLPOINTS instead of VECTOR_SPLINE_FITPOINTS, do the objects render more closely like AutoCAD? If not, please tell me where exactly on the drawing our toolkit differs significantly from AutoCAD.

I have set the flag dwFlags to VECTOR_SPLINE_CONTROLPOINTS so the result still unchanged. The problem is that we have not more informations retreived by your library concerning the VECTORSPLINE in order to get the same result as AUTOCAD. I attach to this message a capture where you can see the significant difference between the VECTORSPLINE handeled by your library (RED CURVES) and those handeled by AUTOCAD (BLEU CURVES). Those splines are more smooth.

Why your library can not retreive all informations concerning the spline from the DXF file?

Thanks
