Hi everyone,
We are working with a customer that is generating some models using grasshopper for which we are to manufacture on our router. The model that gets generated is being sectioned into interlocking pieces similar to this: T-Rex Dinosaur (Anatomically Correct) - Dinosaurs | MakeCNC.com
Where we run into problems is when we export the file out, some residual information gets passed into the new solid file that makes some of the solid pieces open. Not only that, the errors/artifacts that get translated over are extremely hard to repair if they can be repaired at all. In one instance, my CAM/CAD software sees the open solid, but says it can’t repair it. So, I go to delete the face along the edge in question, and once it’s deleted, more faces appear from the intersecting piece that would be there on a complete assembly. Super odd and I’ve never seen anything like that before with any CAD system I’ve used.
We have the rhino files that are generated and a seat of rhino so that we can inspect and manipulate them if necessary. From what tools I’ve been able to find for analyzing the models, they appear to be intact without error on the rhino side.
I’m not sure what to do here. Our CAM software can import most standard solid formats and I experimented quite heavily with STEP and Parasolid. Our CAM system even imports native rhino files, but they import very poorly and create geometry that seems to be generated with grasshopper to get the basic overall shape of the completed assembly.
Any and all feedback would be greatly appreciated. I would upload parts to show, but we don’t have permission to share these files due to intellectual property/copyright concerns. I hope you understand.
Thanks!
