I'm wondering if anyone has written a macro that imports a dxf polyline to a 
sdl spline. It would be very helpful in my current project. I'd write it but 
hey, i'd rather trace. (it'd take me a while to write too).

Dave.

After writing this I went to work on the macro and found (not too quickly) 
that the #read directive needs strings enclosed in quotes, which the dxf 
does not supply. I guess i'll write a c program to convert the dxf directly 
to a spline in an include file.

  No, it needs comma-separated values. The values themselves can be
floating point numbers, vectors and strings.
