A point cloud becomes a Revit model or CAD drawing when a modeler imports it as a measured backdrop and draws real building elements on top of it. The scan supplies geometry. A person supplies the walls, doors, and equipment. That step is called scan to BIM, and it is what turns a capture into drawings a franchise build-out can be priced from.
Key Takeaways
- A point cloud is measured geometry, not a model. Someone still has to draw the building.
- Matterport delivers point clouds through MatterPak or as an E57 file, which opens directly in Revit and AutoCAD.
- Matterport’s own BIM deliverable is modeled to LOD 200, which suits schematic design and early scoping.
- For franchise work the practical output is usually a 2D CAD plan of existing conditions the architect adapts the prototype into.
What is a point cloud, in plain terms?
A point cloud is a dense collection of individual measured points, each with a position in space, that together describe the real shape of a room. Think of it as several million measurements taken at once rather than a picture.
It is not a model. It has no idea what a wall is. It knows there are points arranged in a flat vertical plane at a certain location, and a person or software has to decide that plane is a wall.
How does the data get out of Matterport?
Two routes, depending on what the design team needs.
MatterPak is Matterport’s file bundle. It includes a point cloud, a mesh file, and high resolution floor plans. It is the straightforward option when the design team wants usable files without much fuss.
E57 is a higher density point cloud in a vendor-neutral format defined by an ASTM standard, which means it is not tied to any one software maker. Matterport describes it as supporting millimeter-level accuracy in BIM model creation. It is the option when the point cloud itself is going to be worked in.
Matterport also publishes a plug-in for Autodesk Revit that imports E57, XYZ, and BIM files directly from a Matterport account, which removes a file conversion step.
What actually happens in the modeling step?
The point cloud is loaded into Revit or AutoCAD as a reference. Then a modeler traces it, placing real building elements where the measured points say they belong.
In Revit that means creating walls, floors, ceilings, doors, windows, columns, and where scoped, mechanical, electrical, and plumbing runs. In AutoCAD it more often means producing 2D plans and elevations of existing conditions.
The judgment call is how much detail to model, and it is worth deciding before anyone starts. That level is described by LOD, short for Level of Development, a scale for how much a modeled element is actually committed to. Matterport states its own BIM deliverable is modeled to LOD 200, which is schematic design fidelity, and that it ships a .dwg CAD file alongside the .rvt model.
For deeper detail on choosing a level, see our post on what LOD you need for scan to BIM.
What does a franchise build-out actually need?
Usually less than people assume, and specified earlier than people manage.
For most franchise units the useful deliverable is a clean 2D CAD plan of existing conditions, dimensioned and accurate, that the architect adapts the prototype layout into. Walls, openings, columns, ceiling heights, and the locations of existing utilities are what matter.
A full Revit model earns its cost on larger or more complex units, on second-generation restaurant spaces with significant mechanical work, or where the franchisor maintains a model library across the portfolio.
The mistake worth avoiding is ordering a detailed model nobody opens, or ordering a plan too thin to price from. Both come from skipping the conversation about what the drawings are for.

Frequently Asked Questions
Is a point cloud the same as a 3D model?
No. A point cloud is measured geometry with no understanding of what anything is. A model has walls, doors, and equipment as objects with properties. Getting from one to the other is the modeling step.
Can my architect work directly from the Matterport tour without a point cloud?
For early feasibility, often yes, since measurements can be taken inside the tour. For construction documents they will want the point cloud or a drawn plan derived from it.
What is the difference between MatterPak and E57?
MatterPak is a bundle including a point cloud, mesh, and floor plans. E57 is a higher density point cloud in a vendor-neutral format built for CAD and BIM work. Design teams doing serious modeling generally want E57.
Do we need Revit, or is CAD enough?
For a typical franchise unit, a 2D CAD plan of existing conditions is usually enough to adapt a prototype and price the work. Revit earns its cost on complex units or where a model library is maintained across the portfolio.
What Happens Next
Tell us what the drawings have to support, prototype fit, permit, or pricing, and we scope the deliverable to that. RCE captures the site, produces the point cloud, and hands your architect either a CAD plan of existing conditions or a Revit model at an agreed level of development. Across a rollout the same specification applies at every location.
