Point clouds have become increasingly important in architecture as they allow for accurate and detailed 3D representations of real-world objects and environments. This technology can be used to capture and digitize the physical world, providing architects with the ability to create more precise and informed designs. Point clouds can be created through a variety of methods, such as LIDAR scanning, photogrammetry, or laser scanning.
In Archicad, you can open and convert .xyz and .e57 file formats into objects that are suitable for placement on either the Floor Plan or in the 3D window.
Point Cloud files have versatile applications in various workflows, such as modeling the surrounding environment or terrain. While the standard import method is covered in the article "Importing Point Clouds and Modeling the Terrain," we would like to introduce you to an additional option using CloudCompare based on Miguel Castro Perez's notes.
If you want to find topography data, we recommend using OpenTopography.
