How Do I Make Curves Smooth in Sketchup?

Are you struggling to make smooth curves in Sketchup? Look no further! In this tutorial, we will guide you through the process of creating smooth curves in Sketchup using some handy tools and techniques.

Using the Arc Tool

The Arc tool is a powerful tool in Sketchup that allows you to create precise and smooth curves. To use the Arc tool, follow these simple steps:

  • Select the Arc Tool: To select the Arc tool, click on the ‘Draw’ menu or press ‘A’ on your keyboard. Alternatively, you can find it in the toolbar on the left-hand side of your screen.
  • Draw the Base Line: Click once to set the starting point of your curve, then move your cursor to set the direction and length of your base line. Click again to complete the base line.
  • Create Curves: After drawing the base line, move your cursor away from it. You will see a preview of your curve.

    Click once to set the radius of your curve. You can also type in a specific radius value if needed.

  • Adjust Curve Segments: By default, Sketchup creates a single curve segment. To create a smoother curve with multiple segments, click again to add additional points along your curve. Drag these points to adjust their position and create smoother curves.
  • Complete Your Curve: Once you are satisfied with your curve, double-click or right-click to complete it.

Using Plugins for Advanced Curves

If you need more control over creating smooth curves or want advanced options, plugins can be extremely helpful. Here are two popular plugins that can enhance your curve-making experience:

  • Create Control Points: Click on your canvas to create control points for your curve.

    By dragging these control points, you can adjust the shape and smoothness of your curve.

  • Adjust Curve Handles: Each control point has two handles that allow you to control the direction and length of the curve segment. Drag these handles to fine-tune your curve.
  • Create Additional Control Points: To create a more complex curve, click on the canvas to add more control points. Adjust their position and handles as needed.
  • Complete Your Curve: Once you are satisfied with your curve, right-click or press ‘Enter’ to complete it.
