The way loads are entered on lintels and beams has changed.

Previously lintel and beam calculators required the total span of the applied load.

Specifier now uses Loaded Dimensions (LD) for applied loads, to align with NZS3604 and common industry practice, allowing Specifier to be used with confidence in more use cases:

• Calculator diagrams have been updated and extended to clearly show permitted cases and the relevant loaded dimension formula.
• For most calculations the loaded dimension is simply half the span of the applied load.
• Existing saved calculations have been automatically converted to the equivalent loaded dimension values.

Generating design certificates is now faster and easier with automatic selection and attachment of recommend resources.
