    Geometry/bike drawing app

    Before I bought a new bike, I was comparing geometry of my choices just by looking at the numbers. But I wanted to also see how the bike look, so I wrote a super basic app to draw a bike using geometry data.

    This is the info the app needs:
    • name of the bike
    • wheel diameter
    • head angle
    • seat angle
    • reach
    • stack
    • wheelbase
    • chainstay length
    • seat tube length
    • bb drop
    • fork offset


    Other four optional parameters are:
    • offset_seat
    • offset_head_top
    • offset_head_down
    • debug


    If anyone is interested I can provide more info about this parameters, or anything else.
    The app generates images for each bike from the provided file or a single image with all bikes on top of each other.

    Here is a demo:

    You can download it from here:
    https://www.dropbox.com/s/oujvbybeut7642u/geometry.zip

    The archive includes the app, an example file, and the python source code.

    Cool tool
    Use it, use it, use it while you still have it.

    This is pretty cool. My 11 year old son is really into drawing frames (gets out his protractor, compass, etc..), so he'll probably dig this.

    How many replies did the unicorn thread get before it was sent into space? Any good replies?
