Sketchup Building Point Repack -
BuildingPoint provides official support and specialized training for SketchUp, positioning it as more than just a drawing tool; it is a full ecosystem for architecture, engineering, and construction (AEC) professionals.
Common Steps and Approaches
Go to Window > Model Info > Statistics and click Purge Unused. This is the first step of any repack. It removes components, layers, and styles that are no longer in use but are still being tracked by the software. Step 2: Fix Problems sketchup building point repack
Structural Engineering
For bridge or stadium scans, repacking allows you to overlay finite element analysis (FEA) meshes on top of as-built point data. After importing complex meshes (OBJ, STL, FBX)
SketchUp’s engine relies on faces and edges. When a model has too many edge segments (effectively too many points defining a curve), the file size balloons. This is often referred to as "geometry sprawl." A "repack" is the process of condensing this data. Select all traced lines, right-click, and create a Group
When to run it
- After importing complex meshes (OBJ, STL, FBX).
- Before exporting to real-time engines (Unity/Unreal) or CNC/CAD.
- When the model shows stray edges, z-fighting, or odd shadows.
- When scaling down a model or converting high-poly groups to lower-poly proxies.
- Select all traced lines, right-click, and create a Group.
- Inside the group, use
Draw > Sandbox > From Contoursto generate a surface that snaps to the average of the underlying points.
Quick practical workflow (SketchUp + common plugins)
- Backup your file (Save As).
- Isolate the target group/component.
- Purge unused: Window → Model Info → Statistics → Purge Unused.
- Run basic cleanup:
