CAM Corrections After Model Revision

What does it take to modify the G code After a change has been made in the sketch?

Hi @chuck767 

Thanks for posting! I think an important distinction to make is that the g-code output and the CAM programming within Fusion 360 are separate - the g-code output is created from the CAM programming, but the output is not automatically altered with model changes.

When you make any change in the model workspace, whether or not it actually effects the CAM toolpaths, any unprotected toolpaths will be flagged for regeneration (with the red exclamation point icon) when the CAM workspace is re-entered. The existing toolpaths then need to be regenerated.

After the toolpaths are regenerated, they will need to be post processed again to update the output code for the machine - this will give the new code required to match the model changes at the machine.

So, the general workflow is:

1. Making any model changes will flag ALL existing CAM toolpaths for regeneration.
2. Regenerate the toolpaths (CTRL+G, CMD+G on Mac, right-click the setup or operation and select "Generate").
3. Post the new copies of the toolpaths to create updated output code for the machine.
