marking center point of holes with plasma help.

Can any one guide me in the right direction, to pierce a hole in the center of a circle

I use Hycad mostly for my drawings, Ive tried using “create point” feature to mark out the center of where id want to drill out a hole. But when i load it in sheet cam I doesnt load up that point I added in… the only way i can make this happen is to draw a small circle (.20ish in size) it will cut that…

but my machine doesnt cut small holes round and when you drill them out after they are not in the exact spot as they should be some times.

thanks for your help
