The ENVE website provides a technical drawing of the SES AR In-Route One-Piece Handlebar. In the image below, I've underlayed this image behind a BikeCAD model. By referencing the 150mm dimension I added to the BikeCAD model, I was able to scale the image to match the model. I lined up the stem collar with the stem in the drawing and adjusted the stem to match as best I could. Modeling the handlebar itself was made easier by the fact that various ENVE SES AR handlebars are already included as standard parts in the Handlebar dialog box.
