AutoCAD
You can use AutoCAD to create complicated linework and save that to a DXF file. You may have to save it as a version 2000 dxf or 2002 dxf.
Locate the linework near the 0,0 / origin at the lower left. If your linework is a "few thousand feet away" from the origin in AutoCAD, it will be more difficult to locate in Vectric.
If you are using Vectric or Partworks/Vectric it should be able to open the dxf. I would create any needed text in the Vectric program.
The decimal point seems to be the most important on the z axis... x & y not so much....
