Riscontro — How to Use
Last Updated: January 1, 2026
What Riscontro Does
Riscontro compares Revit model geometry against a loaded point cloud and colour-codes each element by deviation severity. It is designed for BIM coordinators and site engineers who need to verify as-built conditions without manual visual inspection.
Prerequisites
- Autodesk Revit 2025 or 2026
- A project model open (not a family document)
- At least one loaded point cloud (RCS or RCP format) linked into the model
- A 3D view, floor plan, or section active
If the point cloud shows ⚠ in Manage → Manage Links → Point Clouds, it is unloaded. Select it and click Reload before running Riscontro.
Ribbon Location
Riscontro appears on the Avant Leap tab, Riscontro panel.
Workflow
1 — Run Analysis
Click Run Analysis to compare all elements in the active scope against the point cloud.
Optional: Select specific elements in Revit before clicking to analyse only those elements.
Riscontro will:
- Detect all loaded point clouds in the model
- Collect supported element categories (configurable in Settings)
- Filter elements that spatially overlap the point cloud
- Measure the deviation between each element's geometry and nearby cloud points
- Colour-code each element in the active view
- Show a summary dialog with counts and top deviations
Colour key:
| Colour | Meaning |
|---|---|
| Green | OK — within warning threshold |
| Orange | Warning — deviation detected but below critical threshold |
| Red | Critical — deviation exceeds critical threshold |
| Grey | No data — no cloud points were found near this element |
2 — Review Results
Click Review Results to see the full deviation table for the last analysis run.
- Rows are sorted by severity (Critical first)
- Click Export to CSV to save the full report for handoff or further analysis
- The CSV uses
.as the decimal separator regardless of your system locale
3 — Select Deviations
Click Select Deviations to automatically select all Warning and Critical elements in the Revit model. Use this with Revit's built-in Isolate Element or to create a filter for further review.
4 — Clear Colors
Click Clear Colors to remove all Riscontro colour overrides from the active view. The stored analysis results are preserved — click Review Results to re-view them.
To clear both colours and stored results, click Run Analysis → Reset stored results.
5 — Settings
Click Settings to configure:
| Setting | Description |
|---|---|
| Warning threshold (inches) | Deviation at which an element is flagged as Warning |
| Critical threshold (inches) | Deviation at which an element is flagged as Critical |
| Search radius (ft) | Radius around each element to query for cloud points |
| Min point spacing (ft) | Minimum distance between sampled cloud points |
| Max points analysed per element | Upper cap on cloud points evaluated per element |
| Max elements per run | Upper cap on elements analysed in one run |
| Enable zone analysis | Subdivides large elements (floors, roofs) into a grid to detect localised deviations |
| Zone grid size (ft) | Cell size used for zone subdivision |
| Categories | Toggle which Revit categories are included in the analysis |
Click Reset defaults to restore factory settings. Click Save to apply.
Large Element Zone Analysis
For large elements such as floors and roofs, a single deviation value can mask that one zone is well-positioned while another has significant deviation. When Enable zone analysis is on, Riscontro:
- Detects elements whose footprint exceeds 1.5× the zone grid size
- Subdivides the element into a grid of zones
- Evaluates each zone independently
- Reports the worst zone as the element deviation
This means an element is only marked OK if all zones are within tolerance.
Tips
- Run the analysis from a 3D view that is aligned with the point cloud for best colour visibility.
- Use a smaller search radius for interior scans (3–5 ft) and a larger one for full-site exterior scans (8–15 ft).
- For a fresh run after changing models: click Run Analysis → Reset stored results → close the dialog → Run Analysis again.
- Export to CSV after each analysis session for project records.
