The machinability assessment stopped before it finished, so CAM Assist can't list the part's issues. The message shows in the Assessment stage, under Machinability issues and in the status banner.
Couldn't finish assessing machinability.
How to fix it
- In the Assessment stage, click Try again next to the message.
- If it fails again, close CAM Assist. In your CAM package, check that:
- the part is a solid body,
- there is at least one setup,
- the stock body the setup uses still exists.
- Start CAM Assist again.
The Setups stage and Run CAM Assist stay available even though the assessment didn't finish. Severe problems such as gaps in the model or stock that doesn't cover the part haven't been checked, so the run may fail later. The Feature planning stage shows "Hole planning can't run until the machinability assessment succeeds."

If it keeps failing, contact CloudNC support. Include the part file, a debug bundle (see Save a debug bundle) and your CAM Assist log files: see Find your CAM Assist log files.
