Description
Return relativeCoordinate = sectionCoordinate-suppliedOrigin, multiplying by -1 when reverseAxis is true.
Dental specimen and bench-model measurements need an explicit image scale, coordinate origin and geometric convention. A linear taper, chord ratio or calibrated length describes a supplied model and does not establish anatomy or guide clinical treatment.
Return relativeCoordinate = sectionCoordinate-suppliedOrigin, multiplying by -1 when reverseAxis is true.
When to use this tool
Use Canal Model Section Origin Token when checking a supplied research or bench-model dimension.
How to use the tool and how it works
- Enter sectionCoordinate, suppliedOrigin, reverseAxis. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read relativeCoordinate. Use the output convention below.
Return relativeCoordinate = sectionCoordinate-suppliedOrigin, multiplying by -1 when reverseAxis is true. Input coordinates share one linear unit and origin convention.1
| Input field | Meaning and units | Accepted input |

| sectionCoordinate | Section Coordinate | Required. Finite number. |
| suppliedOrigin | Supplied Origin | Required. Finite number. |
| reverseAxis | Reverse Axis | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| relativeCoordinate | Relative Coordinate | Required. Finite number. |

}Limitations and assumptions
- This is translation and optional axis reflection only. No anatomical origin, image registration, rotation or clinical coordinate system is inferred.
- 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 verified specimen and instrument methods, full geometry and professional clinical assessment when the question extends beyond bench arithmetic.
