If your CAM system is detecting overlapping lines or giving you error codes the primary reason for this is that your auto offset feature is toggled on and your CAM system is literally redrawing the design work to accommodate an unnecessary offset. This will give the laser cutter a crisp edge to work from. If you hold Shift while drawing the circle will draw out from the centre and if you hold Ctrl + Alt while drawing the software will ensure you draw a perfect circle. (P.S. Does this have anything with the problem? New Autocad packages will highlight this for you. Which software do you use and which format are the files in? This g-code file contains cut path information such as lead ins, part geometry, cutting speed and power settings. The reason to do this is you want the cut to go right down the centerline of the vectors in these files. Those produced from software capable of exporting vector files are easily interpreted by laser cutters. I've managed to decompress and open it using solid works,.the assembly has 1449 components which I wanna convert to dxf for laser cutting, There's no option to save bodies or save as dxf file I've managed to open it.
