I've designed a particular shape PCB with 2 round corners using arc tools. Since I needed precise dimensions I've set them when I was drawing PCB outline. The problem is that PCB outline now isn't closed and I'm unable to connect open ends becouse they don't match exactly. This create me some problems. I've also tryed to set grid to finest and place ends very near, but nothing, they don't join.
Someone can advice me how I can solve this?
