Door Opening and Maneuvering-Space Studio
Trace how nominal leaf size, frame stops, hardware projections, opening angle, swing, approach direction, and nearby obstructions change the usable plan geometry.
These are configurable learning criteria, not a code determination.
What the drawing can establish
The nominal leaf dimension is not automatically the usable clear opening. Frame stops, projections, and the actual opening position must be checked. The simplified sine adjustment demonstrates why a partly open leaf can reduce usable width; project criteria and hardware details govern.
Clear at 90°

This result is an interpretation aid, not an accessibility, building-code, fire-code, or egress compliance determination. Verify actual hardware, projections, opening force, threshold, approach surfaces, and governing requirements.
