Dry Stone Wall Batter Offset Tool

Description

Multiply height by horizontalPerVertical for oneFaceOffset and by faceCount in {1, 2} for totalWidthReduction.

Simple site geometry approximates an area, section, or volume using ideal shapes. Coherent length units and the distinction between signed and unsigned quantities determine the result's meaning.

Multiply height by horizontalPerVertical for oneFaceOffset and by faceCount in {1, 2} for totalWidthReduction.

When to use this tool

Use Dry Stone Wall Batter Offset when you need one transparent landscape geometry component.

How to use the tool and how it works

Enter height, horizontalPerVertical, faceCount. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read oneFaceOffset, totalWidthReduction. Use the output convention below.

height	Height	Required. Finite number; minimum 0.
horizontalPerVertical	Horizontal Per Vertical	Required. Finite number; minimum 0.
faceCount	Face Count	Required. Safe integer; minimum 1; maximum 2.

Output field	Interpretation	Returned shape
oneFaceOffset	One Face Offset	Required. Finite number.
totalWidthReduction	Total Width Reduction	Required. Finite number.

Limitations and assumptions

The batter ratio is dimensionless; wall stability, base thickness, drainage, and structural requirements are not checked.
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 a surveyed terrain or construction model when irregular shapes, settlement, drainage, and structural performance matter.
