X Carve drills holes in 3 D projects why?

I am using X Carve as my CNC and X Controler as the processor and V Carve Pro as my project set up soft ware and CNCj’s as my execution program. I can’t explain it either, however it is quite consistent in drilling holes in every project. I will try to share this as you requested. I have to figure that out, to do it, as I have not posted many things here on discuss. I greatly appreciate your help with this problem though.
