Engrave Functionality

I came across this vCarve video and was wondering if there is anything is the engrave CAM operation that will do what is shown at 1:30 in this video:

Is this possible with engrave?  Every time I try to use a chamfer mill with pocket clearing the CAM kernel "dies unexpectedly".

Engrave will only give you a contour pass, essentially. To obtain (in Fusion) what is done in that video, you would have to pocket out the part and leave stock on the walls. For instance, assuming you are going to be using a 90 degree (included angle) cutter and you were going .100" deep. You would leave .100 Radial Stock on the walls and use an endmill to first pocket it out. And then go back in and use the Engrave function with a chamfer mill.

Not the prettiest solution or answer, but it's essentially what you've got

EDIT: Just tried using 2D Pocket, and it does appear to somewhat work, although the cycle time is rather...extensive. So, there are your two options. Pocket with an endmill and get all the flat surface, coming back in with a chamfer mill, or B) Using a chamfer mill to do it all and the cycle time will be what it is. I can imagine that a chamfer mill with a flat end (that can cut) should also be able to work

I also tried the 2D pocket clearing but I would keep getting hung up at 9% when the tool path was generating so I figured it just wasn't going to work.  I'll have to give it more time and see what happens.  Thanks for your help!
