    I am writing a programme to create DXF files for import into autocad.
    I need to create a complex three dimensional object with solid colour.
    I have a mesh for the shape I want to make, but I am defeated by the
    way that the dxf file format represents world and object co-ordinates.
    Can anyone tell me how I translate from a set of (x,y,z) coordinates
    into the numbers for the codes (10,20,30 etc .... 210,220,230)
    necessary for the SOLID object.

    Thanks

    Trevor
