Easy Way to cut 3d Models into 2d slices

[CnCustoms]

OK Will do.Im not sure if i have the file in iges or step but i will see if i can export as one of those.I currently using autodesk 2010 so i think i should be able to do it.I will upload the file in a bit.the size of the file or the actual dimensions?I currently have it in 3ds,stl,skp,obj,mtl formats but I think i can convert to almost format.the stl file i have i about 5mbs.Once i upload the file I will pm you all the details if you dont mind.Thanks for your help and your time I do appreciate everything youve helped me with so far.

3ds ,stl or obj is good as well (but less than iges)

any other ideas I hate to bring a old thread back from the dead but I came across sketchup from google.I have a 3d model I would liek to have sliced I also have a slicer plugin But it seems as though sketchup might not be the right program to slice this model.Anyone have a program that I easier to work with that will do this effectively?or nayone have the know how on how this can be done??
