TurboCadCam drawing prob

I do not know if this is off subject are not i am sure someone will
let me know. I am using turbocadcam to do 2.5 inlay cutting in
wood. I like the cam section but the cad does not work well with
me. I am using another drawing program and saving the file in .dxf
format. TCC opens the file with out any problems but i cannot get it
to draw a toolpath for the drawing. I am very green at this stuff so
just bear with me. I was wondering if anyone had any suggestions.
Thanks for all the help Chris Mckenzie
