How to scale in sketchup
Dragging a rectangle's corner handle ensures only size changes, not shape. (Hemera Technologies/ Images)

Google's design program SketchUp has tools for changing the size of objects such as squares and circles, and for scaling textures also. Scaling objects involves applying the "Scale" command which has keyboard modifiers that impact how SketchUp performs the scaling. Texture scaling involves first opening the texture for scaling through a context menu of the surface the texture is attached to. Both kinds of scaling assist you in crafting virtual models that meet your design criteria.

Skill level:


    Scale Geometry

  1. 1

    Click the "Draw" menu then click the "Rectangle" command in that menu. You'll use this shape to learn one way of scaling.

  2. 2

    Click on the drawing canvas to make the rectangle's first point.

  3. 3

    Drag to grow the rectangle to any size you'd like.

  4. 4

    Click to finalise the rectangle.

  5. 5

    Triple-click an edge of the rectangle to select all its edges.

  6. 6

    Click the "Scale" command of the "Tools" menu. The rectangle will display green cubes at its corners and the midpoints of its edges. These are handles by which you can scale the rectangle.

  7. 7

    Click one of the midpoint cubes then drag it. SketchUp will scale the rectangle only along the dimension you specified. For example, if you dragged the sizing handle on the rectangle's long side, the rectangle's shorter sides will shrink or grow.

  8. 8

    Click again to end the resizing.

  9. 9

    Repeat step seven, but this time hold down the "Shift" key. SketchUp will scale the rectangle proportionately. In other words, the rectangle will retain the same original shape. The "Shift" key modifier locks SketchUp into proportional scaling mode.

  10. 10

    Repeat step seven again, but this time hold down the "Control" key as you drag the sizing handle. Unlike the previous two scaling operations SketchUp will shrink or grow the rectangle about its centre, instead of about one corner.

    Scale Texture

  1. 1

    Click the "Rectangle" command from the "Draw" menu then click on the drawing canvas to plot the rectangle's starting point. You'll scale a texture that you apply to the rectangle.

  2. 2

    Drag to grow the rectangle to a size you want then release to complete the rectangle.

  3. 3

    Click the "Materials" command of the "Window" menu then click a texture from the gallery that appears.

  4. 4

    Click the rectangle to apply the texture to the rectangle.

  5. 5

    Right-click the rectangle and click "Texture" followed by clicking "Position." SketchUp will display four brightly coloured buttons. One of these buttons lets you scale the texture.

  6. 6

    Click and drag the button whose icon is shaped like a parallelogram. The rectangle's texture will change in size.
