Introduction: 8020 Chopper
8020 is an industrial prototyping extrusion made from aluminium. I used it here to construct a chopper by joining the extrusions with water-jet cut plates of 1/4inch aluminum.
Step 1: Choose and Design the Type of Bike Frame You Wish For
Here are some of the options we designed at an MIT IAP class in 2003.
The CAD files are all included in this step.
Step 2: Choose the Connecting Parts From the Part Library or Design Your Own.
These parts will be cut from 1/4 or 1/2inch thick aluminum plate using a water-jet.
We have a be nice policy.
Please be positive and constructive.
I realize its been 13 years, but I've been trying to view these files, and I can't find anything that works with these DXF files. how were they created?
I've tried inkscape, librecad, freecad, autodesk viewer, and www.zamzar.com. inkscape and librecad just show nothing. The rest generate error messages which tell me essentially nothing beyond "it don't work". Eg:There was an error processing your file. F1GL3LVBRDEP27R3GX.dxfPlease Try a Different FilePossible issues could be:
• Your file may have external references which are not
currently supported. • You may have used an older file version, which may not work. • Your file may be corrupted or encrypted.
Inkscape works fine with DXF files, and its a free download from Mozilla.
