Point Repack — Sketchup Building

When a building is scanned using a laser scanner or photogrammetry, the resulting "Point Cloud" contains millions—even billions—of points. SketchUp is a surface-based modeler, not a point cloud engine. Attempting to import a raw .LAS or .E57 file directly often causes SketchUp to crash or lag severely.

As the architecture and construction industries embrace digital surveying, the challenge of importing heavy LiDAR data into SketchUp has become a central technical hurdle. The process often referred to as a "Point Repack" is actually a workflow involving decimation, indexing, and optimization. This allows designers to take millions of scan points from a building site and "repack" them into a manageable format for SketchUp. sketchup building point repack

Open-world games (e.g., Assassin’s Creed, Cyberpunk 2077) use photogrammetry. The "repack" is the secret step where raw drone scans become NPC-navigable geometry. When a building is scanned using a laser
