You should use separate 3d modelling software for it. There are several freeware available such as 3DPlus 2, OpenFX, Varcon CAD, Ayam to name a few

I don't belive there is a way to make 3-D objects from photoshop, unlesss you wish to make a layered object with diffrent image formats. I do suggest many 3-D programs, to make 3-D shapes and project your image on them, such as 3-Ds Max, or Autodesk Inventor, Google Sketchup, Milkshape 3-D.
