Creating curves in Sketchup can add depth and dimension to your designs. Whether you’re a beginner or an experienced user, learning how to make curves in Sketchup for free is a valuable skill. In this tutorial, we will explore various methods to create curves in Sketchup and unleash your creativity.

Method 1: Using the Arc Tool

The Arc tool is one of the easiest ways to create curves in Sketchup. To access this tool:

  4. Move your cursor to define the radius or length of the curve.
  5. Click again to finish drawing the arc.

Tips:

  • Bezier Curves: Hold down the Ctrl key (Command key for Mac users) while drawing an arc to create a Bezier curve, allowing you to adjust its handles later.
  • Precision Input: Type in exact values for radius or length by typing them into Sketchup’s measurement box at the bottom-right corner of the screen.

Method 2: Utilizing Plugins

If you want more advanced curve creation capabilities, there are several plugins available for Sketchup that can enhance your workflow. Here are two popular ones:
