Description
Return a fin's supplied angular projection.
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 a fin's supplied angular projection.
When to use this tool
Use Facade Solar Fin Projected Depth when checking the stated opening, projection or clearance geometry.
How to use the tool and how it works
- Enter finDepth, angleRadians. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read projectedDepth. Use the output convention below.
Return a fin's supplied angular projection. Require finDepth >= 0; projectedDepth = depth*abs(sin(angleRadians)).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| finDepth | Fin Depth | Required. Finite number; minimum 0. |
| angleRadians | Angle in radians on the specified axis/sign convention. | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| projectedDepth | Projected Depth | Required. Finite number. |

}Limitations and assumptions
- The angle must match the intended reference direction; this is not full solar geometry, shading performance or structural assessment.
- 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.
