Rafter with Distributed Snow Load
Inclined rafter (3-4-5 triangle) carrying a globally horizontal distributed snow load (engine direction="member" maps to global +x, not along-rafter); exposes the counter-intuitive V/M/N diagram that arises when the load direction does not follow the member axis.

All reaction values are computed by the StatIQ structural engine, not generated text. Signs follow the solver's convention: a positive Ry acts upward, a negative Ry downward; a positive M is counter-clockwise.
