gerber-writer 0.3.4

A library to write Gerber files

Purpose

A Python library for writing Gerber files.

Its benefits over writing Gerber files directly from the spec are:

• No need to read the 200 page Gerber format specification.

• A much simpler API than the Gerber format specification -8 pages vs 200,

• Built-in pad with all common shapes.

• User-defined pad for special shapes

• 100% compliance with the specification, rev 2022.02.

• Conservative, robust output files. Risky constructions that fail in some buggy implementations are avoided.

• Include meta information need for fabrication, such as what pads are via, in a standardized manner.

• Input methods verify whether the parameters comply with the Gerber spec.

• Stateless input (the gerber_writer takes care of the Gerber states).

Example:

from gerber_writer import DataLayer, Path
profile_layer = DataLayer('Profile,NP')
profile = Path()
profile.moveto((0, 0))
profile.lineto((150, 0))
profile.arcto((160, 10), (160, 0), '-')
profile.lineto((170, 10))
profile.lineto((170, 90))
profile.lineto((160, 90))
profile.arcto((150, 100), (160, 100), '-')
profile.lineto((0, 100))
profile.lineto((0, 0))
profile_layer.add_traces_path(profile, 0.5, 'Profile')
with open('gerbers\profile.gbr', 'w') as outfile:
        profile_layer.dump_gerber(outfile)
