Hi everyone,
I need to do splines in a dxf file with a script, so I use python dxfwrite : It
seems that it is the best thing that exists... But impossible to be sure.
But I have a problem with : when I run this sample script :
---------------------------
#!/usr/bin/python
from dxfwrite import DXFEngine as dxf
spline1 = [(0.0, 0.0), (1.0, 0.0), (2.0, -1.0)]
dwg = dxf.drawing('spline.dxf')
dwg.add(dxf.spline(spline1))
dwg.save()
---------------------------
I have this output :
amel@debian:~/job/RR/pl/06$ ./spline.py
Traceback (most recent call last):
