Brick Bond Half Module Offset Tool

Description

Return alternating half-module brick-course offset.

Building quantity takeoffs depend on inclusion/exclusion rules, repeated modules, joint placement and material thickness. Net area and ideal layer resistance are limited model quantities; actual fit, heat/moisture behavior and construction performance require the full assembly and measured material properties.

Return alternating half-module brick-course offset.

When to use this tool

Use Brick Bond Half Module Offset when checking the stated material, layer, module or takeoff convention.

How to use the tool and how it works

Enter module, course. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read offset. Use the output convention below.

Return alternating half-module brick-course offset. Require module > 0 and nonnegative whole course; offset is zero for even course and module/2 for odd.^[1]

Input field	Meaning and units	Accepted input
module	Module	Required. Finite number; strictly above 0.
course	Zero-based integer course index; odd courses receive half a module offset.	Required. Safe integer; minimum 0.

Output field	Interpretation	Returned shape
offset	Offset	Required. Finite number.

Limitations and assumptions

The first indexed course is zero; this is one layout convention, not a complete bond pattern, structural design or masonry specification.
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 drawings, specifications and suitable assembly/material analysis for actual procurement, hygrothermal performance or construction.
