Your file is attached. The error, I believe, is coming from some pretty tight splines in your DXF. When the profile of one of these is selected, the direction of cut is goes screwy. As you will notice I have a lot of operations which I did to keep my mind straight on which profile failed and I had to return to it, touch the direction arrow, to have it reverse and correct itself. I know it is all over the place but you can redo it if you want to. Just remember if you get an error, go back to the geometry select and reverse the arrow of motion. Sometimes, if you select a lot of paths at one time, this will become difficult. This is why I have quite a few path definitions. You can check to be sure you have all paths covered by doing a simulation, click on the end icon and then look straight down on it to see if the path was cut. Please note all I did was to define the paths, all other configurations I will leave up to you. File is attached.
