Exporting / importing splines of any degrees
Posted: 10 Feb 2009, 13:37
Hi
I am using cadimport.net to import and export draw from/to dxf files.
Everything is ok but the splines.
Actually I can CORRECTLY import/export ONLY splines of DEGREE 3.
All other kind of splines are wrongly converted (and it looks like they are managed as if 3rd degree).
For instance when i export the splines, i set control points and knots.
The degree should be authomatically inferred from the knots. But it is not.
For instance a spline with 8 points and 10 knots (0, 0 ...6 values... 1, 1) is a spline of degree 1
but when i export it, it writes a dxf with degree 3 (!) and 12 knots (0, 0, 6 values, 1, 1, 1, 1)
that by the way is not correct even for a 3rd degree
Any help would be very appreciated.
