Open lines are closed by sheetcam

I have this eagle who has a lot of lines in it. I made the sign with Coral Draw and in my drawings I cannot find anything wrong with the file. In sheetcam, it’s closing all the open lines to closed shapes. Not sure what i’m doing wrong. Even if I try with no offset.

Sorry, I missed this post. If you are still working on this go to Options->application options->drawing import. Reduce the ‘import link tolerance’ value to something less than the smallest gap you want left open.

No problem sir. I checked what you said and it’s at .0004 My lines are not that small. They vary from an inch to longer. Not sure if I understood that correctly. Tks
