Part does not seem to exist in CAM

[BiggerHammer]

Hello, all. I'm using BobCAD v23 mill, with Artsoft.

I created a brake light matrix to hold LEDs (create a cube, then create a pattern of small cylinders, then subtract the cylinders to create a 3d part with a staggered hole pattern), then went to CAM. When I tell CAM to computer a toolpath, it doesn't seem to do anything. When I tell iot to verify, the simulator window comes up blank. Posting comes up with a very brief program:

M05
G00 G91 G28 Z0.
G91 G28 Y0.
M06
M02

(END OF FILE)
(END OF PROGRAM)

M30
%

So, it looks as though CAM cannot see the part that I have created. I'm sure that I'm making a very basic mistake, but I can't see it. How can I get my part into the CAM section of the program?

Thank you.

BobCAD tech support is helping me; it looks as though my problem is that I did not tell BobCAD what the stock geometry is.

In your cam tree all i see is feature engrave, which isnt going to work on a solid model

id create a new layer, set that layer to active, go to utilities and extract edges from soilid, click the model, right click and hit ok. Now hide the layer with the solid model on it

Now you can select all the upper or lower pockets and either use feature drill or feature pocket
