I am working with output from drone mapping software producing a large OBJ. The goal is to clip a portion out of the OBJ. I’ve tried everything in the mesh editing toolbox: repairing, rebuilding, boolean split, etc. - no success.
Anyone have similar issues and/or found a way to perform reliable, clean splits on large meshes?
Hi @Vanko_Studio,
To provide help, we’ll need to see the .obj file. Better yet, provid the .3dm file that contains mesh you want to split and the cutting object.

Hi @Vanko_Studio,
The issue I see that that you don’t have a single mesh, you’ve got 20. And each of those is disjoint.
Before splitting, you’re going to need to get these meshes joined into a single valid mesh.
I’m not sure Rhino has enough tools to clean up this mess. You might need to run this through another too such as MeshLabs.

Thank you, Dale! Unfortunately, MeshLab can’t handle these large meshes. Appreciate your time!
Hi @Vanko_Studio,
Rather than using a drone-generated mesh, perhaps some existing topo mesh would be better?

Would be great for models that don’t require too much accuracy as GIS data is only good to +/-3m or so - not accurate enough for this application.
Appreciate your help!
Hey there, Brian - THIS WORKS! Thank you so much!
