There are various reasons for wanting to produce a representation of the camera focal plane in a physical coordinate system with the sensors oriented as they reside in the assembled instrument. The first reason is engineering diagrams used for fabrication and assembly of the camera. The second is visualization for quality assesment, data analysis, or science verification purposes. For reasons motivated herein, these two corrdinates systems cannot be the same for LSST. This document presents the coordinate transform to be applied in translating between the two coordinate systems: 1) the camera engineering coordinate system and 2) the camera data visualization coordinate system.
