MEASURED QUANTITY SENSITIVITY

Board foot — board length scenarios.

How does changing board length affect board foot when the other inputs stay fixed?

What this decision changes

This measured quantity or supplied dimension enters the method on its stated unit basis. Other inputs stay fixed so its effect can be separated from net deductions, stock constraints or purchase rounding. Method basis: One board foot is 144 cubic inches. Enter the dimensions used by your supplier; nominal labels are not automatically converted into actual dimensions.

The focus is board length. All other shared inputs remain fixed for each evaluated range.

Evaluate your supplied alternatives

Start with your measured plan and selected product data. The initial values and range are illustrative. Each scenario changes only board length; the other entered values stay fixed.

Display units

Measured plan and product inputs

Entered board thickness

mm

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Entered board width

mm

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Board length

m

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Board count

Supplied comparison range for board length

Lower supplied comparison value

m

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Upper supplied comparison value

m

Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

Nine evenly spaced values are evaluated. Whole counts are rounded to distinct integer scenarios. Values between the listed samples are not calculated.

9 evaluated scenarios

Baseline: Lumber volume — 40 board ft. Rejected combinations remain visible below.

Quantity to plot

Each bar is one actual calculated lumber volume. Horizontal values: board length in m.

Read the evaluated results

Read calculated demand, whole purchases and exact detail lines separately. This specific input may change quantity continuously, cross a purchase step or make the stated geometry or stock fit invalid.

Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
Enter a comparison range on the focused input's stated unit and quantity basis.
Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.
Open an evaluated scenario in the full calculator to save its original inputs and quantity breakdown to a browser material project.

Keep the comparison within scope

Compare measurements or already specified alternatives. Quantity sensitivity does not establish material suitability or construction requirements.

Uses supplied geometry, product properties and purchasing specifications.

Does not choose or certify construction dimensions, spacing, loads or regulatory requirements.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
