Hi FiL, that truck PDF file was created by Danny using a program called: "Creo Elements/Direct Modeling Personal Edition".

See these previous threads:

That Personal Edition version is available for free:

If you don't like that one, another option is ViaCAD 2D, which is quite inexpensive ($39.99): http://www.punchcad.com/c-12-consumer-cad.aspx
