Description
Return two door outer-edge projections about an offset hinge.
Architectural openings and clearances depend on measured boundaries, projection axes and a caller-supplied comparison criterion. A positive geometric margin is distinct from demonstrating code compliance, safe access or a complete door-swing envelope. Plan lengths and projected dimensions must not be mistaken for full spatial measurements.
Return two door outer-edge projections about an offset hinge.
When to use this tool
Use Architecture: Door Leaf Clearance Hinge Offset when checking the stated opening, projection or clearance geometry.
How to use the tool and how it works
- Enter leafWidth, hingeAxisOffset, openingDegrees. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read result. Expand result to inspect the returned fields.
Return two door outer-edge projections about an offset hinge. Require leafWidth > 0, hingeAxisOffset within leaf and openingDegrees in [0,180]; normal = (width-offset)*sin(angle), along = offset+(width-offset)*cos(angle).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| leafWidth | Leaf Width | Required. Finite number. |
| hingeAxisOffset | Hinge-axis distance from the hinge-side leaf edge, constrained within leafWidth. | Required. Finite number. |
| openingDegrees | Opening Degrees Unit: deg. | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| result | Object containing the returned operation-specific members listed below. | Required. Object. |
| result.outerEdgeNormalProjection | Perpendicular projection of the outer leaf edge about the supplied hinge axis, not actual clear passage. | Calculated result member: number. |
| result.outerEdgeAlongProjection | Outer Edge Along Projection | Calculated result member: number. |

}Limitations and assumptions
- This describes one supplied planar point, not clear opening, collision detection, accessible width or safe door operation.
- Outputs are nested inside result. Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use complete measured plans and a qualified architectural/engineering assessment with the applicable requirements for real construction or safety decisions.
