Internal CAM Kernal Error while using 3D Adaptive on Mac

I've looked through a lot of other threads and cannot seem to find the fix to this issue.

Any time I use 3D Adaptive, I get the error "Internal CAM Kernal Error", regardless of tool I use. I have tried using a sample tool from thee fusion library and get the same message.


I know that this issue has been a result of using Windows 7, but I am having this problem on either OS. My macbook running macOS Monterey and my work computer running Windows 10.


This is the error message with debug:

Feature flags: metrology-survey setup-sheet-viewer

I have no problem running 2D Adaptive, but I would like to use 3D so that it is model aware as I progress through smaller tools. I'll attach a file with a simple pocket.


Any help on this is much appreciated!

Hi @lukesmit695 


Thanks for posting. 


I'm able to create a 3D adaptive toolpath for the below-attcahed model. Please have a look at the attached file.
