Here’s an illustration I keep tinkering with. I helped a friend and colleague on this project with SketchUp modeling. He wanted an illustration to show how it was driven by the need to squeeze a new HVAC system into an existing Manhattan apartment. I modeled the HVAC system crudely from 2D drawings without fixing clashes and what not, and I keep tinkering with how to present it. These require multiple images assembled in Photoshop with masking and transparency.
