How to apply thickness to imported surface model (stl,obj or any format) and make it solid for 3D printing in creo 3.0 Parametric? Help!

I use educational version creo 3.0 parametric.

I have an orthotics project going on that we want to try 3d printed model on broken wrist. I used 123D catch to 3D scan my hand, I downloaded stl, obj file of my hand from 123D catch. I removed undesired materials of the model in Meshmixer and exported to creo 3.0

Now, I want to increase the thickness of the surface model exported from meshmixer and meshlab.

I couldn't make any editing in the software (no thickness applied). I want to make the model solid by applying 5mm thickness.

 

But, my friend could apply thickness to this surface model in solidworks. What he did was:

import into solidworks > copy surface (move by 5mm in desired direction) > select outer loop of first surface > extrude perimeter 5mm (up to other surface) > knit surfaces and form solid > export as stl file (Now, its useful for printing)

I have attached the 3d scan file edited in meshmixer, surface model of scanned hand(ready to export in creo)


I would be very thankful if any one could help me with suggestions!

Cheers,

Thanks!
