EPS (Postscript) to Gerber conversion. Why weren't all the round pads converted to flashes on import?
1 Comment
[QUOTE]When I import the attached eps file and click the box for flashing while doing so --- not all the circles get flashed, some stay as polygons.
I seem to be able to select all those that were not converted by using "convert to flash" selective and specifying eclipse.
Is there a faster way? And why weren't all the round pads converted to flashes on import?

Thanks for sending me a sample EPS file. Ghostscript performs the parsing and generates the boundaries which are in turn used by FAB 3000. The 'real problem' with the inconsistent flashing arises from the unnecessary complexity of your generated Postscript files.
For example, here's the standard postscript code to draw a single circle:
Note: Circle center (351,260) with radius 0.8; units are in points.
If you look at your generated Postscript file, a single circle will appear as this complex sequence (this is a circle located at 351,260 radius 0.8 which did not flash).
As you can see from the unnecessary complexity from you Postscript file, it's even difficult for me to manually follow that code & determine if it will result in a circle. Which means that complex code makes the circle detection algorithm (within ghostscript) much less likely to succeed.
Note: The only reason FAB 3000 can manually detect those circles (using convert to flash command) is because you have chosen a command that specifically tells FAB 3000 to create a circle out of any boundaries you selected. You could select any polygon shape (like an octagon, star, etc.) and if you tell FAB 3000 to make it a circle -- it will.
In the end, keeping data simple results in better efficiency.
Thanks again.
