OBD Data Art

IDEO, Volkswagen and MIT held a Data Driven Hackathon in January, 2014. One of the data sets shared was 30 days of OBD (on-board diagnostics) data. The part of the database I used had around a half million rows. I decided to convert some of the data to lines in AutoCAD using AutoLISP. This AutoLISP code snippet shows converting the data into variables, then drawing a line in 3D space for each data row using the values to control position, angle, length, color, layer, & thickness of each line.AutoLISP code snippet

I then took the resulting DWG into Revit and applied some different visual settings. These are some glamour shots of the model:shot1
