MEASURED QUANTITY SENSITIVITY

Fence post — solid run length (exclude gates) scenarios.

How does changing solid run length (exclude gates) affect fence post 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: A straight run includes both end posts. Shared corner and gate posts must be accounted for in a full project.

The focus is solid run length (exclude gates). 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 solid run length (exclude gates); the other entered values stay fixed.

Display units

Measured plan and product inputs

Solid run length (exclude gates)

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.

Specified maximum post spacing

Where to get this value

Copy this specification from your supplied design or product documentation. This tool does not select spacing, fixing patterns or structural requirements.

Supplied comparison range for solid run length (exclude gates)

Lower supplied comparison value

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

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: Posts in this run — 5 posts. Rejected combinations remain visible below.

Quantity to plot

Each bar is one actual calculated posts in this run. Horizontal values: solid run length (exclude gates) 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.

Only quantities from supplied dimensions and specifications are calculated.

No material-property reference values are bundled; obtain product values from the selected supplier's data sheet.

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