Mechanical 3D/2D Modeling & Piping

I have a set of mechanical parts that need to move from concept into production-ready documentation. What I need from you is two-fold: First, create precise 3D models of each part and the full pipe routing in STEP format so I can drop them straight into our master assembly...
