I’m trying to open a 3mf file using Scene.FromFile(“myfile.3mf”) or scene.open(“myfile.3mf”) and i always get the error “cannot open this file” without any more detail.

Do you have an idea ?

Hello,

Hotfix through nuget would be the best for me.

Is it possible to know the root cause ?

The root cause of the issue is that your 3MF file is missing metadata. Although this is currently allowed in new specification, old specification requires metadata to be present in files when we added support for 3MF.

We just removed the metadata checking in the hot fix.

We have built the hotfix 24.7.1, you can get it from nuget now.

Thank you, it is working with the hot fix.
