Hello all,

I would really appreciate some suggestions on working with bone, I have a solid bone model (in both IGES and STEP) format. I am trying to "shell" the bone and "thicken" it by 2mm. I have tried a number of options including:

- shell and thicken

- offset

- cuting the bone in half and deleting the end face, kniting the surfaces and then thickening

I am trying to split the model into two parts,

1) The first 2mm depth of bone from the surface to be one cortical bone (material property)

2) The internal material of the bone to be cancellous bone (material property)

Everything I try does not to work succesfully, I would appreciate some input from others.

I have uploaded a few versions of the bone to dropbox (and also attached them below to this post) if anyone can help, thanks. I look forward to your suggestions.
