The attached part is representative of the blood volume within major vessels in the body. I am attempting to offset each of these surfaces by 1 mm, and then delete the blood volume, to re-create the actual vessel. I started with an imported .stl and used ScanTo3D to create the surfaces. I then filled the ends of the surface to create the current solid body. I hoped to shell outward, but it throws an error and highlights the faces unable to shell. So, I took the remaining faces and tried to offset the surfaces. I hoped I could offset most of the outer surface and then simply fill in the holes. However, that didn't work. I can offset some of the faces by selecting them one-by-one, but this is a VERY tedious process. Anyone have any suggestions?
Chris,
Though Geomagic was quick at offsetting the surfaces, I still needed to have my final part in Solidworks for other design purposes. Geomagic cannot export a solid part file that Solidworks can interpret so I would have to go back to the mesh stage anyway. So, I found how to offset a mesh in Solidworks. So, I no longer import the first mesh, transform in into a surface, and then offset that surface to get the second surface. Instead, I import the first mesh, offset a copy of that mesh (using Edit Mesh) and create surfaces from each of my two meshes (using Mesh Preparation Wizard and Surface Wizard).
Thanks for everyone's input.
