Export assembly into STL’s with the setting “On File Per Body” results in duplicated files

[wagener_olivier]

Hello Fusion 360 community,

I am currently experiencing a strange behavior, and I am not completely sure if this is intended or if I do something in an unexpected way that triggers this behavior.

In short, I model up bigger assemblies in smaller components which I then reuse multiple times. When I export the complete assembly into STL’s, with the setting “On File Per Body” I get on file for each body in every assembly times the number I copied the assembly.

E.g. in my minimal example shown here, I would expect getting 4 files as a result, but I get 4 x 4 files. So if I open all the files at the same time e.g. in Blender, it initially looks like I have 4 blocks, but every block is 4 times the same body which I then have to clean up…

OriginalThe first block pulled appart

The first Blender screenshot shows how the exported project looks initially, the second after I pulled the first block appart. In this example, the clean up work is manageable. But my current real project results in 800+ single STL files and it is just impossible to clean up.

Thanks for reading and helping out,
Olivier
