This clip discusses the coordinate system and basic rules for tilts and decenters within WinLens3D.
We discuss tilts on individual surfaces, including fold mirrors, and their effect on the reference axis. This is followed by a discussion of component level tilt, showing how to change defaults for individual elements.
We note in particular that a mirror can have both surface tilt and a component tilt - something very useful for modelling scanners, where the surface tilt sets up the basic geometry and the component tilt allows us to simply model the scanner motion.
