I had an organically shaped object 3D scanned. The company scanned the inside surface and I created a solid from this. I can’t remember exactly what steps I took within Rhino to thicken the surface and create the solid. The scanned surface started as 12 MB. I know I reduced the mesh from 65000 or so, to about 20,000. The solid is over 900 MB, which makes rendering fairly slow. All boolean operations have failed. Immediately, I need to trim the top and get rid of the jagged edge, as seen in the first pic. The second pic shows how the individual surfaces are highlighted when the object is selected.
Ultimately, I’m designing a product that will be a liner to fit inside this cup. I will need to offset the inner surface and thicken that offset. I just don’t want to have to keep working with a 900 MB file. I still have the original scanned surface file, so anything can be redone.
What is the best way to either start over or reduce the file size of what I currently have? If I have to manipulate the mesh in a different software, I’m okay with that. If I can do it all efficiently in Rhino, all the better.
Thank you in advance.
