How to Merge Models in Google Sketchup

Merging two or more SketchUp models together lets you move those models as a unit when you attempt to move just one. This behaviour lets you create complex objects formed from several separate models. For example, you could merge a house's foundation model with the walls model, and merge those with a roof model to complete an entire house model. The SketchUp tool that makes this possible is the "Make component" tool. Besides giving you the means to make multi-model structures, the "Make component" tool lets you keep the faces of a single model from distorting when you move the model.

Skill level:


  1. 1

    Open SketchUp, then click the "File" menu's "Open" command.

  2. 2

    Navigate to and double-click a scene file containing at least two models to load the models into SketchUp.

  3. 3

    Click a model then click the toolbar's "Move tool." Drag the model so it intersects with another model with which you'd like to merge it.

  4. 4

    Drag the mouse around both models.

  5. 5

    Right-click and click "Make Component." SketchUp will display a dialogue box showing options for the component.

  6. 6

    Type a description for the component. For example, if you're merging the roof of a house with its foundation and walls you might call the component "CompleteHouse."

  7. 7

    Type a description for the component in the "description" text box.

  8. 8

    Click "OK" to complete the component. SketchUp will display a blue box surrounding all parts of the model.

  9. 9

    Click the component to select it then click the "Move" tool.

  10. 10

    Click on any part of the component then drag to move it. All parts move together as a single unit. This indicates that the models are merged.

  11. 11

    Right-click the component and click "Edit." This lets you temporarily open the component to scale and move or rotate one of its parts. SketchUp will display a wireframe black box surrounding the component, indicating that it's still a component.

  12. 12

    Click one the component's models to select it for editing.

  13. 13

    Click either the "Move," "Scale," or "Rotate" tool on the toolbar then drag on the selected model to modify it. For example, if the component you made consists of a doorway and its door you could click the door model and rotate it so it appears open.

  14. 14

    Right-click the black box then click "Close" to tell SketchUp you're done editing the component. The black box will turn blue.

  15. 15

    Click one of the models then click the tool you used in step 13.

  16. 16

    Drag on the model to perform step 13's operation. This time, the entire component is transformed instead of the individual model. This means the component's individual models are once again merged together.
