Is there any cad tool for simulating or calculating a vehicle track or turning circle for Draftsight?  Or a standalone program that can produce an output suitable for Draftsight?  I've goolged and found free tools for Autocad, Microstation, BricCad, ZWCad.  Would any of those run with Draftsight?  Files seem to be .LCF or .LSP or exe.

Thanks
