What determines the total quantity of parts in an input 3D model?

October 14, 2019 - 7:55pm #1

As "CAD Model Best Practices" says, In general, the CAD model used as input for the Model Target Generator should contain a maximum of 10 parts. If the input 3D model is created with AutoCAD Mechanical, the parts can be specified by BOM and Part Lists. But if the 3D model is created by 3ds Max, and be exported as a FBX, what determines the quantity of parts in it? A submesh is a part? I imported one of my fbx file, and found that there are 350 parts in it!

What determines the total quantity of parts in an input 3D model?

I exported the test model from 3ds max as a stl file. When importing the stl file into 3ds max again, it shows that only one object in the 3ds max scene. Then I imported the stl file into the MTG, this time it shows that there are six parts in the model. So it still confuses me how to control exactly the number of parts in a model (because there is a limitation on it).

Hi,

Usually the number of 3d meshes that the 3d max scene contain. On import MTG also performs some optimization which will actually show a smaller number than in 3d Max.

Thank you.
