Hi catlin mc. Yes this is the same explosion I was working with a while back only reworked a little. The three parts on the left were modeled in Rhino while the one on the right was done in Amapi. Two of the parts done in Rhino are simple revolves and the third is basicly a torus with the bottom half sliced off. The one part on the right was an extrusion done in amapi. I have already over promised myself with tutorials, but this one should be short so I will make up one. Don't be impatient.
