Increasingly I am finding a need to model hip roof truss package. Currently my methodology, [that felt like a George Bush word], is to model the common trusses using Objective, then dive into the painfully complex method of modeling individual trusses, opposing ends.

In a typical residential hip roof truss package the last 8 to 12 feet 90° to the common trusses with bottom chords in hangers off a girder truss, [same profile as the commons.] As the roof "walks" around corners, inside or out, the complexity gets exponentially more complex. [see screen shots]

There has got to be a better way!!, and I'm hoping someone has been here before and can offer up some advice on a better way I'd be very appreciative!
