From a calculator to roof framing software

A single-purpose calculator returns an isolated length or angle. Roof framing software should retain the relationships between building dimensions, pitch, supports, roof surfaces and individual timber members. Changing a primary dimension can affect common rafters, hips, jacks and cutting documents.

Capabilities to evaluate

• Geometry: gable and hip roof layouts, pitch, ridge and overhang relationships.
• Timber elements: common rafters, hip rafters, jack rafters and supporting elements.
• Workshop details: support cuts, notch references, section dimensions and element IDs.
• Visual review: linked 2D and 3D views for spotting geometric inconsistencies.
• Output: element cards, cutting lists and project documentation.

Practical workflow

Start by entering the building footprint and roof geometry. Review the framing arrangement and openings, inspect critical connections and cuts, then prepare element documentation. Verify the output against the construction drawings before fabrication; geometric modelling is not a substitute for structural engineering.

How Krokwio fits the workflow

Krokwio focuses on framing geometry and preparation information. Its application includes roof layouts, 3D visualization and selected workshop documentation features. Feature availability can depend on the current version and access level. For a narrowly scoped calculation, start with the rafter calculator or birdsmouth guide.

Questions before selecting a tool

Does it use unambiguous measurement references? Can it represent multiple roof planes and openings? Does it identify real elements rather than theoretical full-length lines? Does its output clearly distinguish geometric assumptions from structural verification?
