Yes, you can use the "generate geometry from NC code" function, Newbie.
This will generate a wireframe rendering of the toolpath. This is not exactly the same as seeing a drawing of the part, necessarily.
I think that this "reverse post" function only reads industry standard G00, G01, G02 and G03 codes. In some cases, this will cause the omission of some stuff.
Bobcad comes with a bunch of sample files. You can post them and then use the geometry from NC function (in the NC menu) and compare what you get, forwards and back.
