How to place a point cloud in Archicad

Issue description

You have a point cloud file in XYZ or E57 format and need to import and open it in Archicad.

Solution

Placing a point cloud in Archicad involves importing the point cloud data, which will transform it into a placeable Archicad object, and then positioning it within your project.

Important: Archicad has basic point cloud handling abilities. Files larger than 2–4 GB may cause performance issues; CloudCompare is an open-source tool that allows editing and optimizing point cloud data before importing into Archicad. For advanced point cloud workflows, we recommend using BIMmTool, which provides additional import and editing tools.

1. Go to File > Interoperability > Import Point Cloud.
2. Browse and select the point cloud file you want to import.
3. Click Create or Create and Place to proceed. (Create will simply load it as an object for later use)

4. For this example we will select Create and Place.

   

5. You can then decide if you would like to place the point cloud at its own internal origin or at the Archicad project origin.

   TIP: You can use Point clouds in combination with the native survey point.

   

6. Open the 3D view to confirm the point cloud appears correctly.
7. Adjust the floor plan cut plane in View > Floor Plan Cut Plane Settings if the point cloud is not visible in the plan.
8. If relocation or reorientation is needed, use Move, Rotate, or Align tools to fine-tune the position of the point cloud. For alignment with your project, you might use known reference points or levels.

Important: Point Clouds serve as a reference for modeling and analysis but are not included in published drawings or layouts.
