The UW EcoCAR team uses Siemens NX 12.0 (Unigraphics) as their CAD software. Most of my work took place in a dedicated “constrained” model, where I communicated with members from 9 other project teams to modify and integrate their component design assemblies into the main model. I used GD&T principles to ensure conformity with CAD model specification and EcoCAR Mobility Challenge competition metrics.
