Cad/Cam program problem

I am new to Cad and CNC and have an issue with Desknc that I need some help
with.

I am drawing a basic bearing block that has 4 mounting holes 3/8” from each
edge and

one hole dead center that is ¾” in diameter. The block is 2” square. I am
using Adobe

Illustrator CS3 to design the block. When I export my file as a DXF and
import it into

Desknc I get an error message “Explode all splines before importing”. I
don’t understand

this as I have used Turbocad, Corel Draw as well as AI and get the same
message. Is

there another Cam program I might test drive to get a better handle on this
or does

someone on the group know what I need to do in AI to fix this?
