Hi chemical-database,

Sorry about your trouble.

You just tell me it is not working, which gives me very little to work with.
There are a few steps, and each has a result. When do you not get the expected result, which would perhaps help to get it working? Please let me know.

Such information should also be detailed if you contact the tech support

If the trouble you encounter is not a workflow but based on technical problems, like hardware or software code). Here, I can guide you as much as possible through the steps.

I used the current releases and the same WiFi (same "band" and frequency)
In Cinema 4D, I have set up the Preferences> Extension> Forger File Transfer.
I restarted both apps after set up, and I was able to round-trip my model. I hope we get this done for you as well.

One question: can you airdrop files? (I presume an iPad to Mac workflow)

All the best
