New Machine Build- Autocad to Mach3 problem with arcs

[LTP]

Hi,
We about to build a new CNC lathe similar to this one. YouTube- The CentauroT90 CNC AUTOMATIC COPY LATHE DEMO VIDEO for bats Im looking into the CNC side of it at the moment. I have a demo copy of Mach3 Turn, Lazy Cam, Autocad 2000i and solid works 2004. I am writing the programs in autocad then exporting as a .dxf to lazy cam which converts them to .tap from there I load them into mach3. When i write programs which are made up of straight lines everything is ok and mach3 simulates it correctly. However as soon as i try to get it to machine a curve it all goes bad. The drawing in Autocad looks like this:
then when i upload it to lazy cam then to mach3 it end up like this When I draw a straight line drawing it looks like this in Mach3 Im not sure what im doing wrong, i just cant seem so be able to simulate a arc. Any help would be greatly appreciated.

Thanks,
Lachie G

Try using LazyTurn instead of LazyCAM.

Thanks a lot for that, i have installed it but when i try to upload my .dxf files into it i get an error "Warning, no appropiate turning profile was found." That happens when i try to upload a .dxf file which has curves. When i import a .dxf file with no curves it opens fine im just unsure on how to export as a .tap file for Mach3.

Thanks a heap,
