How Do You Make a Curved Surface Smooth in SketchUp?

by

In SketchUp, creating curved surfaces is a common practice. However, sometimes these surfaces may not appear as smooth as desired. In this tutorial, we will explore various techniques to make a curved surface smooth in SketchUp.

1. Soften/Smooth Edges

If you have already created a curved surface but it appears jagged or rough, the first step is to try softening or smoothing the edges. To do this:

  1. Select the curved surface by clicking on it.
  2. Right-click and choose “Soften/Smooth Edges” from the context menu.
  3. In the dialog box that appears, adjust the angle slider to increase or decrease the level of smoothing.
  4. Click “OK” to apply the changes.

This method works well for simple curved surfaces, but for more complex shapes, additional steps may be required.

2. Increase Segments

If softening/smoothing edges didn’t produce the desired results, another option is to increase the number of segments in your curved surface. This can be done by:

  1. Select the curved surface by clicking on it.
  2. Right-click and choose “Entity Info” from the context menu.
  3. In the Entity Info panel, look for “Segments” under “Statistics”.
  4. Increase the number of segments by typing a higher value in the appropriate field.
  5. Press Enter to apply the changes.

The more segments you have, the smoother your curved surface will appear. However, keep in mind that increasing segments can also impact performance and file size.

3. Use Bezier Curves

If your curved surface is more complex and requires a higher level of precision, using Bezier curves can be a great solution. Here’s how:

  1. Select the pencil tool from the toolbar.
  2. Click on the starting point of your curve.
  3. Click and drag to create handles that define the shape of the curve.
  4. Repeat this process to create additional points and adjust the handles as needed.
  5. To close the curve, right-click and choose “Close Curve”.

Bezier curves provide more control over the shape of your curved surface, allowing you to create smooth and precise curves.

4. Utilize Plugins

In SketchUp, there are various plugins available that can help you achieve smoother curved surfaces. These plugins offer advanced tools and features specifically designed for creating complex shapes. Some popular plugins include:

  • Fredo6’s Curviloft: Provides a wide range of tools for creating lofted surfaces, skinning, and more.
  • SUbD: Allows you to create subdivision surfaces with smooth and continuous curvature.
  • Catmull-Clark Subdivision: Offers subdivision algorithms for creating smooth organic shapes.

By utilizing these plugins, you can enhance your workflow and achieve even smoother curved surfaces in SketchUp.

Conclusion

Making curved surfaces smooth in SketchUp is essential for achieving realistic and visually appealing models. By following these techniques such as softening/smoothing edges, increasing segments, using Bezier curves, and utilizing plugins, you can elevate the quality of your designs and create captivating curved surfaces.
