Why are fusion Archive files with the extension .f3z not allowed to be uploaded on Grabcad, but .f3d files are?
I have been wondering this for a while now. When I upload models, I try to give a few different file formats, and as a Fusion360 user I would like to upload the native Fusion files to Grabcad. I can upload individual parts in a Fusion archive file with the extension .f3d, but when I try to upload assemblies with a .f3z extension I am told the file type is not supported. I understand that .f3z files might be harder to parse for grabcad, and the 3d viewer is not likely to support them, but I would still like to upload these files for other Fusion Users.
Does anybody have a good reason why they are not supported? Or is it just something Grabcad has neglected to support based on demand.

It is likely a combination of technical challenges (like handling file complexity and storage constraints), a focus on file formats with broader user bases, and possibly lower demand for Fusion 360 assemblies on the platform. GrabCAD has a history of supporting a wide range of formats, but sometimes specific features or file types might get deprioritized in favor of more universally used ones.
If this is something important for your work and collaboration, you could also suggest it to GrabCAD's support team or community forum, as user feedback often helps platforms evolve and prioritize features.
