Sketchup Building Point Link !!top!! (Tested - Version)

While there is no single feature officially named "Building Point Link," the phrase likely refers to one of three core SketchUp workflows used to connect points or manage model geometry. 1. The Inference Engine (Point Snapping)

SketchUp’s Inference Engine is the primary way to "link" or snap to specific building points. When you move the cursor near geometry, the engine provides visual cues to help you align points accurately: Endpoints (Green): Snaps to the start or end of a line. Midpoints (Cyan): Snaps to the exact center of an edge.

On Face (Blue): Ensures you are drawing exactly on a surface.

Intersection (Red X): Links to the point where two edges cross. 2. Linking and Relinking Models (LayOut)

If your query refers to linking a building model to documentation, this is managed in SketchUp LayOut. sketchup building point link

Model Reference: You can link a SketchUp file to a LayOut document. If the original building model changes, the "Link" allows you to update the reference so your drawings stay current.

Relinking: If the file path changes, you can use the Relink button in the Document Setup > References window to re-establish the connection between the drawing and the 3D model. 3. Joining Points to Create Faces

To manually "link" points to form a building’s structure, you use the Line Tool (L): Clicking one endpoint and then another creates an edge.

When you "link" several edges to form a closed loop on a single plane, SketchUp automatically creates a Face, which can then be extruded using the Push/Pull Tool. While there is no single feature officially named

If shapes overlap, you can use the Split tool in LayOut to create shared vertices (points) that link the geometries together. Find the Center of Things in SketchUp

You're looking for a useful guide on linking building points in SketchUp. Here are some steps and tips to help you with that:

Can I link points across two different SketchUp files?

No. You must import the other file as a Component reference. Once imported, you can use the Alt-click technique to link your active drawing points to the reference model points.

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. Select the Move tool

2.1 The Inference Lock (Shift + Control)

To manually force a point link:

  1. Select the Move tool.
  2. Hover over the source point (e.g., the corner of a window).
  3. Hold Shift (or Ctrl on PC for copy) to lock the inference.
  4. Move your cursor to the target point (e.g., the edge of a brick).
  5. Result: The window corner is now mathematically linked to the brick edge.

1. Native Workflow: The "Survey Point" & "Axes" Tool

Best for: Basic site placement and aligning a model to a specific geo-location.

Before extensions, users had to "link" building points manually using native tools.

  • How it works: You import a CAD file or location data. You use the Axes Tool to align the Green/Red axes to your building's specific orientation. You then use the Survey Point (found in the Model Info > Geo-location) to define a fixed reference point that does not move when you pan/zoom.
  • Pros:
    • Built-in (Free).
    • Sufficient for single-building projects where high-precision GIS data isn't critical.
  • Cons:
    • Not a "Link": It is a static setup. If you move the base point in your civil engineering software (Civil 3D), SketchUp does not update automatically.
    • Confusing Interface: The SketchUp "Survey Point" is often misunderstood; many users accidentally move the origin point rather than the survey point, breaking the geo-location.

3.1 SketchUp Pro’s "DWG Reference Manager"

If your "point" comes from an engineer’s CAD file:

  • Link Method: File > Import > "Create Reference".
  • The Benefit: The CAD points are now externally linked. When the engineer updates the DWG, SketchUp prompts you to reload it. All your walls and columns linked to those points update automatically.

3. Print & Reinforce “Point Links”

  • Print on 110 lb cardstock (thicker than paper, yet foldable).
  • Before cutting, score along all fold lines (use a ruler & empty ballpoint pen).

7. Recommended Extensions for Advanced Point Linking

  • Parametric Modeling with Fredo6 Tools (e.g., Curvizard, GhostComp) – adds constraint-like behavior.
  • MSPhysics – for mechanical point-to-point linking with joints.
  • Dibac – architectural plugin that maintains wall/roof point relationships.
  • SketchUp IFC Manager – for point-linked BIM export.
