Mold cavity from facet feature, point cloud?

I'd really appreciate some insight into this problem.


I'm trying to model a mold cavity for a kidney that I segmented. I can import the kidney into Creo either as an STL or a point cloud (.pts). I attached both. I tried saving the STL as a .prt file and bringing it into the mold cavity creator, but that didn't work, which was not entirely surprising. I've looked into ways to clean up the STL/solidify it/solidify the point cloud, but I haven't been able to get anything to work. Any thoughts?

Thanks.

After a little more digging and a helpful tip from a lab mate, here's how I got it to work:

1) Use Meshlab (a free mesh editing program) to simplify, smooth, and clean up the STL. Resave.

2) Import the STL into an empty part file in Creo. Save as a shrinkwrap. This creates a solid part defined by the boundary of the mesh.

3) Create mold like usual.

I suspected this to be the case. I tried Cadkey to make a solid, but it did not import as a usable model. Creo has very little control over facet models. The shrinkwrap model is probably the best solution available.
