Hi all,

I'm working on a big CAD processing job - think thousands of small hand held size objects that make up a large piece of machinery (about the size of an average house).

I have successfully exported and tessellated the CAD, using Unreal Data-smith, and converted it to FBX.

Unfortunately not all instances of geometry were persevered - or perhaps ever authored that way - so the data contains many duplicate objects in different positions in world space.

I'm looking for a way to find each object that is the same as another so I can replace them with an instance point, then clean up just one version of and object and instance it in unreal - saving loads of authoring time and performance in engine.

There is some level of naming and hierarchy, which allows me to break it all into separate pieces or components, but they are all just named “surface##”.

Any advice, even just an idea of where to start would be amazing.

Thanks
