Start from the design model
Use an SAF or IFC export from the architectural workflow. The workflow needs no extra plugin or special modelling convention.
From architectural model to analytical model.
The NodeSnap workflowNodeSnap connects three parts of structural model preparation: converting the architectural export, carrying changes forward, and checking the result against its source. Built around ArchiCAD, SAF and IFC, and LIRA-SAPR.

Use the workflow from the first export through the next design revision.
01
Automatic conversion
Extract geometry, member sections, materials, and supports from an architectural export. Align members, resolve junctions, and snap nodes for the analytical model.
Explore conversion 02Revision sync
Compare a newer architectural revision with the existing model. Update the changed elements while retaining loads and engineering assumptions.
Explore revision sync 03Element verification
Compare each element with its source. Check geometry, axes, sections, and materials, and inspect suspicious results before analysis.
Explore verificationA practical route into LIRA-SAPR.
Prepare and inspect the analytical model
Conversion handles the repetitive geometric work. Verification helps the engineer examine how the analytical elements relate to the source.
Keep the model current
When the design changes, compare revisions and review the affected elements. Retain the engineering work already attached to the analytical model.
One workflow. Different responsibilities.
Automation supports model preparation; the structural engineer remains responsible for the engineering interpretation.
| Task | NodeSnap helps with | Your team decides |
|---|---|---|
| Model preparation | Extracting and connecting analytical geometry | Whether the resulting idealisation represents the intended structure |
| Design revisions | Updating changed elements and retaining loads and assumptions | Whether the changed design requires different loading or assumptions |
| Element review | Comparing geometry, axes, sections, and materials with the source | Which discrepancies need correction before analysis |
