The Non-Sequential section of the manual covers "Source" objects (like LEDs or Filaments) and "Detector" objects. It explains how to run Monte Carlo ray traces to simulate real-world lighting environments and evaluate "Color Over Angle" or "Luminous Intensity." Advanced Features and Programming
Depending on your version, here is exactly how to access the manual.
"Alignment tolerance exceeded," the machine droned in a synthesized voice. "System critical failure."
Most engineers skip tolerancing until the end. The manual’s chapter on "Monte Carlo Analysis" explains how to set compensators (e.g., focus shift) and interpret 90% yield predictions.
