I am trying to create a mesh from the surface of another mesh (the attached .3dm file). This file contains a lot of errors. There are 2,331 total edges, 657 naked edges and no non-manifold edges. When the Perspective view is set to Shaded, Rhino renders the model beautifully. What I find frustrating is that if Rhino can render the surface beautifully, why can it give give me a mesh based on that beautiful surface?
I have been attempting to do this for two solid days. I’ve tried dipping into Meshlab, but this too has lead me to a dead end. I strongly suspect that Rhino can do this, only I don’t yet know what I should be doing to get the result i’m looking for.
My objective is to 3D print this object, but I don’t want to print it as a solid object. It’s the base of a telephone and needs to be printed with walls that are 1mm (more/less) thick. Hence my desire to pull a mesh off the surface of the model.
There is a similar posting on this site that suggests using ExtractPt and Patch, but this results in an object that is so distorted it is truly not recognizable.
Fixing all the naked edges en masse produces bad results. The alternative is to fix them a pair at a time, but there are 657 of them. Also, that’s not an even number, so there must be some single naked edge somewhere.
Again, Rhino renders the object beautifully. All I want is a mesh of the beautiful surface.
