Introduction

Artwork has been writing tools for processing RS274X files for over 25 years. During that time we have come across many files that are extremely large and difficult to process - sometimes the reason these files are so large and difficult is because they are written out poorly by the layout software that produced them.

Over the years then, we wrote many routines to detect these issues and to "clean" them prior to passing the data to the program code that actually manipulates (converts or rasterizes) the data. Eventually we gathered the various pre-processing routines -- which had been distributed between various application programs -- into a single library that we now place in front of all of Artwork's Gerber related processors.

We are releasing this collection of cleaning and conditioning routines as a stand-alone executable called split274x. Both GUI and command line options are available. The library is also available to OEMs who wish to tightly integrate the pre-processor into their software.

Who Would be Interested?

If you offer photo mask or PCB services and you routinely accept Gerber data from your customers you might be interested. Especially if you have customers that send files that bog down your photo plotter.

Or you might be an equipment manufacturer -- say inspection -- and you need to import large Gerber files to generate the "golden" reference.


Preprocessing Functions

Dynamic Range - Format Statement


Redefined Apertures Mid Stream


Redundant Aperture Definitions


Remap Out-of-Range D-Codes


Filter Closely Spaced Vertices


Break High Vertex Count Polygons


Redundant Layer Directives


Redundant SR Directives


Fix Poorly Defined Arcs
