The problem is that SPLINE entity in the DXF file is a proprietary AutoCAD
entity. Only the control points and some other points used by AutoCAD to
define the SPLINE, are listed in the DXF file. In AutoCAD (at least in the
old version I am using) you cannot "EXPLODE" a SPLINE entity into line and
arc segments, which OpenSCAD understands. The best you can do with the DXF
file is to edit it and make a list of the control points. If you look at
the DXF file you will find a series of numbers something like this:
The number after the "11" is an X coordinate and the number after the "21"
is a Y coordinate of a control point that was used to create the spline.
In the picture below the blue line is the SPLINE and the red lines connect
the control points.
If you can post a link to the DXF file I will see if I can convert it into a
series of short line segments or an AutoCAD POLYLINE, which OpenSCAD can
Fred helped me. In the end, he ignored my poorly crafted DXF and
created his own from my bitmap file.
Thank you, Fred!
