If you have ever struggled with lines that won’t connect, faces that refuse to close, or components that shift mysteriously, you are likely missing the fundamentals of point linking. This article will serve as your ultimate guide to understanding, mastering, and troubleshooting the "Building Point Link" process in SketchUp. Before we dive into techniques, let’s define the keyword. A SketchUp Building Point Link refers to the specific connection between two or more geometric endpoints (vertices) within a building model. This "link" is what tells SketchUp that Point A belongs to the same object as Point B.
Draw a line from Floor 1 to Floor 20. SketchUp will draw a line in 3D space, but it won't "link" to the 18 floors in between. sketchup building point link
Imagine you have a 20-story building. You have a floor plate component copied 20 times. You need to add a curtain wall that links the top right corner of Floor 1 to the top right corner of Floor 20. If you have ever struggled with lines that
If you do not see the colored inference dot, do not click. If you are not holding Shift to lock an axis, assume you are wrong. If you are drawing inside a group and need to connect to the outside, press Alt . A SketchUp Building Point Link refers to the
Without a proper , your model will leak. Leaky models crash, refuse boolean operations (Solid Tools), and produce ugly renders with light bleeding through the cracks. Method 1: The "Inference Lock" Technique for Point Linking The primary way to create a building point link is using SketchUp’s Inference System. Here is the step-by-step professional workflow: Step 1: Activate the Line Tool (L) Select the Line or Tape Measure tool. Hover over the endpoint of an existing wall. Step 2: Wait for the "Endpoint" Inference Look for the colored circle (Red, Green, Blue, or Cyan). The pop-up label will say "Endpoint." Do not click yet. Step 3: The "On Edge" Inference Move your cursor slowly along the axis direction. SketchUp will show a dotted line. This is the inference lock. Step 4: Execute the Link Click only when the inference line snaps to the exact coordinate of the target point.
Hold the Shift key to lock the inference direction. This ensures that your new point links perfectly vertically or horizontally to the existing building point. Method 2: Healing Geometry with "Close Open Points" Sometimes, imported geometry breaks existing links. SketchUp has a hidden hero for this: Edge Utilities (available via Extension Warehouse) or the native Find Intersections tool.
