With Aspire all you would do is highlight the model and the outer circles -- use the select vector box and hit go. I don't know how Artcam works but all you want to do is set it to make a pocket cut around the model instead of cutting the model out. Should be as simple as checking the right box or selecting the right toolpath. It's minor.
It looks like you have created the relief, just need to create a 3D relief toolpath, roughing and finish, not a pocket toolpath. There is a preview function where you can preview the toolpaths you create, no need to carve something and discover it is not doing what you want.
ArtCAM pro dates back to 2008, did you get a pirated version with a Chinese CNC? I would recommend updating to something a little more current. My licensed version Of ArtCAM dates to the years AutoDesk owned it, 2018, but Artcam is not currently available legally. Carveco is the current equivalent, but very expensive, there are cheaper versions such as Carveco Maker that can be had for as little as $15/mo, with not long term commitment. Vectric’s VCarve is also a good choice.
