Sketchup Building Point Link

Groups and components change how point linking behaves. Geometry inside different groups/components is isolated: endpoints in separate groups do not join even if they occupy identical coordinates. This isolation is intentional—allowing modular design and preventing unintended merging—but it means that “linked” points across groups require intentional strategies. To align elements in different groups, designers either move groups to precise coordinates using the Move tool and inference snaps, use nested components placed within a common parent, or temporarily explode groups to connect geometry, then regroup. Components also allow parametric-like reuse; when a component is edited, all instances update, which effectively links their internal points conceptually via the shared definition.

Indicates contact with a surface or line without a specific vertex anchor.

The term is not just a menu command; it is a philosophy of workflow. It refers to the various methods, extensions, and native tools used to establish permanent, intelligent links between specific geometric points (vertices, endpoints, intersections) within a building model. sketchup building point link

While SketchUp's native tools provide a solid foundation, the true power of building point linking emerges when you leverage the extensive ecosystem of extensions developed specifically for precision modeling.

Length snapping or poor zoom distance caused an incorrect inference selection. Groups and components change how point linking behaves

Align your model axes with a known control point. Best Practices for Point Links in SketchUp

Move your cursor slowly along the axis direction. SketchUp will show a dotted line. This is the inference lock. To align elements in different groups, designers either

"Snaps attach to each other front side to front side. As you approach another Snap, visual cues help show what will happen. When the Snaps are close enough they will snap into place with an orientation based on the Alignment Direction of the target Snap."

"A Snap is a custom point you can add to a group or component," explains SketchUp's official documentation. "Once added, a Snap allows you to both position and orient objects at the same time. Snaps can help you create models with components that are easy to place, layout, or assemble."
