Description
Add drawingDatumAbsoluteElevation to drawingElevation for absoluteElevation.
Architectural quantities depend on dimension references, area boundaries, slopes, and construction allowances. A component calculation can describe a proposed geometry without establishing code compliance, structural adequacy, or buildability.
Add drawingDatumAbsoluteElevation to drawingElevation for absoluteElevation.
When to use this tool
Use Drawing Elevation Datum Offset when you need one explicit architectural geometry component using a common measurement basis.
How to use the tool and how it works
- Enter drawingElevation, drawingDatumAbsoluteElevation. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read absoluteElevation. Use the output convention below.
Add drawingDatumAbsoluteElevation to drawingElevation for absoluteElevation.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| drawingElevation | Drawing Elevation | Required. Finite number. |
| drawingDatumAbsoluteElevation | Drawing Datum Absolute Elevation | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| absoluteElevation | Absolute Elevation | Required. Finite number. |
{
"input": {
"drawingElevation": 2.5,
"drawingDatumAbsoluteElevation": 100
},
"output": {
"absoluteElevation": 102.5
}
}Limitations and assumptions
- Both values need compatible units and reference meaning; no vertical datum conversion, survey adjustment, geoid model, or actual benchmark is verified.
- 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.
