Hi Dale, i guess what is confusing is that the database "actual design" resolution can be set. I use mils so it defaults to 1. In my gerber settings I use 3:5 and that works. I am curious though. If the database is set to 1 does that mean that the minimum supported resolution will ultimately be 1 mill for the gerbers assuming 3:5. What about if something is on a sub 1 mil grid like 1/2 a mil, I wonder if there would be a rounding error ? I have seen some designs done in allegro where the design is still done in mils but the accuracy is set to 2. and others where it is set to 3. I guess my question is what is best 1 ,2 or 3 with respect to database accuracy. It seems like for the gerber output the database accuracy is the determining factor for leading integers.... Thanks Paul.![]()
