Why Point Cloud Heatmap exists
Checking a model against a scan is done by eye, in section, one wall at a time. You cut through, look at whether the points sit on the wall face, form an opinion, and move on. It works, it is slow, and it produces a judgement rather than a record - which is awkward when the question is whether the as-built matches the model well enough to build on.
How Point Cloud Heatmap works
Open a view containing both the walls and columns you care about and the point cloud data covering them.
A confirmation dialog explains the three steps before anything runs - scan the clouds, analyse the deviations, apply the colours.
Every wall and every column in the view - architectural and structural - is matched against the overlapping scan points and colour-coded by what share of those points sit on the wrong side of the modelled face: green under about a third, yellow up to two thirds, red beyond that.
Openings are accounted for, so a door or window does not read as a deviation.
Reset Heatmap restores the original appearance when you are done.
Before
Model-versus-scan agreement is assessed wall by wall in section, and the result is an opinion.
After
The whole view is colour-coded by how well each element agrees with the scan, so the disagreements find you.
When to reach for it
- Verifying a model of an existing building against the survey it was built from.
- Refurbishment work where the as-built deviates from the drawings.
- Producing a visual record of where model and scan disagree, for a client or a contractor.
What it does not do
- It analyses walls and columns, architectural and structural. Floors, ceilings, roofs and MEP are not colour-coded.
- It needs both point clouds and walls present in the active view - with either missing it stops and says so.
- Points more than 150 mm from any modelled face are not matched to it, so a wall that is badly out of position can end up with no data rather than a red badge. Scans are downsampled and capped per cloud so the analysis stays tractable.
- Analysis on a large view with dense scan data takes time, and there is a progress dialog for that reason.
- The colours are overrides on the view, applied in one transaction - Ctrl+Z reverses the run. Reset Heatmap is for later, when the undo stack has moved on.
- Reset works from a backup file the analysis writes for that view. Run the heatmap twice and the second run overwrites the backup, so reset takes you back to the state before that run rather than to the original. If the backup cannot be written the colours are still applied and reset has nothing to restore from.
Questions
- How do I compare a Revit model to a point cloud?
- Manually it is a series of sections and a judgement call. This matches the scan points to every wall and column in the view and colours each one by what share of its points sit on the wrong side of the modelled face - so the metric is agreement, not distance.
- What do the colours mean?
- Green is close agreement, yellow is moderate deviation, red means the model and the scan disagree substantially at that element. The thresholds are fixed bands rather than something you tune per run.
- How do I remove the colours afterwards?
- Ctrl+Z reverses the run, because the overrides all go on in one transaction. Reset Heatmap is for later, once the undo stack has moved on - it works from a backup file written for that view, so it restores the state from before the most recent run rather than the original appearance.
