Gerber 85 Win 7 64 Bit Full
Sheldon Cibrian
The Gerber format is an open, ASCII, vector format for printed circuit board (PCB) designs.[1] It is the de facto standard used by PCB industry software to describe the printed circuit board images: copper layers, solder mask, legend, drill data, etc.[2][3][4]The standard file extension is .GBR or .gbr[1] though other extensions like .GB, .geb or .gerber are also used.
My first issue pertains to exporting the gerber files in a standard 2:3 Format. I work in mils and trying many combinations of database accuracy I have found no
way to export in 2:3 positional format. I am wondering if it is even possible ?
As you can see there are two separate lines. One indicating the Format & one indicating the Units. If I edit the cadence gerber file to look like this then my CNC package has
no issues reading the data.
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
