How Do I Stretch an Arc in SketchUp?

by

SketchUp is a powerful 3D modeling software that allows users to create and manipulate various shapes and objects. One common task that users often encounter is stretching an arc to achieve the desired shape or size. In this tutorial, we will explore different methods to stretch an arc in SketchUp.

Method 1: Using the Scale Tool

If you want to stretch an arc uniformly, the Scale tool is a great option. Follow these steps:

  1. Select the arc you want to stretch by clicking on it.
  2. Go to the Tools menu and select the Scale tool or simply press ‘S’ on your keyboard.
  3. Click on any of the endpoints of the arc and drag it outward or inward to increase or decrease its size respectively.
  4. To maintain proportions, hold down the ‘Shift’ key while scaling.

Method 2: Using the Move Tool

If you want to stretch an arc asymmetrically, you can use the Move tool. Here’s how:

  1. Select the arc by clicking on it.
  2. Go to the Tools menu and select the Move tool or press ‘M’ on your keyboard.
  3. Click anywhere on the arc and move it in any direction to stretch it as desired.

Method 3: Using Control Points

If you want more control over each point of your arc, you can use control points. Here are the steps:

  1. Select the arc by clicking on it.
  2. Right-click on one of its control points (small squares) and choose ‘Make Control Point’ from the context menu.
  3. Click and drag any control point to stretch the arc in any desired direction.
  4. Repeat the process for other control points until you achieve the desired shape.

Tips and Tricks

Here are some additional tips to enhance your stretching experience in SketchUp:

  • Group Your Arc: If you want to stretch multiple arcs together, it’s a good practice to group them. This way, you can apply transformations without affecting other geometry in your model.
  • Use Guides: SketchUp provides guide lines that can help you align and stretch arcs accurately.

    Simply activate the guide tool by pressing ‘G’ on your keyboard and create guides by clicking and dragging from any edge or point of your arc.

  • Utilize Numerical Input: For precise stretching, you can use numerical input. After selecting the arc, type in specific dimensions or values in the measurement box at the bottom right corner of your SketchUp window.
  • Beware of Distortion: Be cautious when stretching arcs too much, as it may distort their curvature. It’s always a good idea to regularly check and adjust using reference images or measurements if necessary.

In Conclusion

Stretching an arc in SketchUp is a straightforward process when you know the right tools and techniques. Whether you prefer uniform scaling with the Scale tool, asymmetrical adjustments using the Move tool, or more control with control points, SketchUp offers multiple options to achieve your desired results.

Remember to experiment with different methods and utilize additional features like grouping, guides, numerical input for better precision. Now go ahead and stretch those arcs with confidence!
