At its core, SketchUp is a surface modeler that relies on a mesh of polygons to create the illusion of solid form. In this context, the "building point" is the vertex—the intersection where edges meet to define a face. For the SketchUp user, the mastery of the software is largely a mastery of point placement. The inferencing engine, arguably SketchUp’s most powerful feature, acts as an intelligent guide for point placement, snapping to endpoints, midpoints, and intersections with mathematical precision.

While the manual placement of points remains standard for design, the definition of a "building point" has expanded with the advent of reality capture technology. In contemporary architecture and construction, projects frequently involve renovation, restoration, or addition to existing structures. Here, SketchUp’s ability to handle "point clouds" becomes essential. A point cloud is a massive dataset comprising millions—or even billions—of points in three-dimensional space, each possessing coordinate data (X, Y, Z) and often color information (RGB).

Here’s a called “Building Point” — designed to streamline precise placement and alignment of architectural elements.
