Here's the easiest way to draw a sphere

Don't draw one! Instead, download a sphere from the 3D Warehouse. There are thousands of components available in the 3D Warehouse, including many spheres.

If you prefer to do things yourself

Here's a step-by-step manual method you can use:

  1. Use the Circle tool

    to draw a circle on the ground plane. The first time you do this, you'll find it easiest if you start your circle at the origin point (the point where the red, green, and blue axes intersect). With the Circle tool still selected, hover way out along the top edge of the drawing until the circle cursor turns red or green, and then press and hold the Shift key to lock that inference direction (both of these inference directions are perpendicular to the ground plane).

  2. With the inference direction locked, draw a second circle inside the first, but make it a little smaller than the first. Then use the Select tool to select the face of the first, larger circle.

  3. Select the Follow Me tool (on the "Tools" menu, click "Follow Me"), and then click the face of the second, smaller circle. A sphere should result.

  4. Use the Erase tool to erase a point on the edge of the first, larger, circle. That circle should be entirely erased, leaving the full sphere.

Here's a little trick you can do with the Follow Me tool. Instead of preselecting the original circle, select the Follow Me tool, click the face of the second circle, press and hold the Alt key, and then click the face of the first circle.

Want to smooth the circle? If the circle looks a little jagged, try adjusting the rendering options:

  1. Open the "Window" menu.
  2. Click "Display Settings."
  3. Try reducing the size of the extensions and endpoints, or turning them off.
