Overview

  • Agree the survey scope and control, register the scans, establish coordinates, then model and check the required elements.
  • A model-to-cloud comparison checks consistency with the scan. It does not independently prove that the survey is accurate.
  • Record concealed areas and missing coverage rather than presenting inferred geometry as measured.

A point cloud gives the modeler measured surface data. A useful Revit model also needs a clear survey scope, reliable coordinates and agreed rules for what to model.

From survey to Revit

  1. 01
    Agree the capture scope

    List the rooms, external areas and services needed for the design. Record access restrictions and which concealed conditions need separate investigation.

  2. 02
    Check the survey package

    Ask for the coordinate basis, control information, registration report and coverage record. Resolve unexplained offsets or gaps before modeling the affected areas.

  3. 03
    Link the point cloud

    Revit links indexed RCP or RCS files. Autodesk documents several positioning options; choose the one that matches the agreed survey and model coordinates, then check known locations.

  4. 04
    Model the required elements

    Follow the element list and intended model uses. Keep observed geometry separate from assumptions. Do not infer pipe specifications or concealed connections from a visible surface alone.

  5. 05
    Review and deliver

    Check the agreed elements against the cloud and record deviations, exclusions and unresolved areas. Deliver the model with its coordinate basis, survey date and review record.

Start with a sample area

For our Scan-to-BIM service, share the available survey files and intended use. We can agree the elements, tolerances and review method on a sample before modeling the rest. If automation is proposed, its output needs the same checks.

Frequently asked questions

Can I open a point cloud directly in Revit?+
Revit links indexed RCP and RCS files. ReCap can prepare supported raw scan formats. Confirm file compatibility and coordinate positioning with the software versions used by the team.
How is Scan-to-BIM accuracy checked?+
Check survey control, registration and coverage first, then compare the required modeled elements against the cloud at the agreed tolerance. Record the checking method and any inferred or inaccessible areas.
Can a scan reveal concealed services?+
Ordinary surface scans do not show services hidden behind opaque finishes. Mark these areas as unverified and agree any additional investigation with the project team.
