DXF generator for involute gears

thingiverse

A small Python script, called "gearsgen," creates DXF designs for involute gears. By default, the generated gear is displayed in a (tkinter) window without an output file. The program is licensed under GNU GPL and does not affect the DXF files you generate with it. Developed during Hackathon 2.0 at Metalab, Vienna, you can find more information about the event here: http://metalab.at/wiki/Hackathon. To use "gearsgen," run python gearsgen.py followed by options and arguments such as -n for number of teeth (default = 5), -m for module (default = 1.0), -c for clearance (default = 0.0), -a for addendum offset (default = 0.0), -p for pitch (default = 0.0), -s for spacing (default = 0.0), -e to generate only DXF entities without header or footer, -l for the name of the DXF layer for generated entities, -x and -y to adjust coordinates in the DXF file, -r to rotate the gear by a specified angle in degrees, and -f for the name of the DXF file to generate. If no -f option is used, the generated gear will be displayed in a (tk) window scaled to fit the viewport.
