Drawing an inner tube

Drawing an inner tube
Advanced tasks, such as drawing a cone or inner tube, require experience with several SketchUp tools and features. You should be competent with the following tools and features before attempting to draw an inner tube:
  • The Circle tool
  • The Select tool
  • The Follow-Me tool
  • Inference

One common way to draw a inner tube is:

  1. Draw a circle on the ground plane at the origin. This circle will be used as a path used to draw the sphere. The size of this circle does not matter.
  2. Use the Select tool to select the face of the circle and press the Delete key. The face is deleted.
  3. Select the Circle tool.
  4. Move the cursor to the origin. The cursor should snap to the origin.
  5. Move the cursor up the blue axis (above the circle on the ground plane). The cursor should turn green or red.
  6. Hold the Shift key to lock the Circle tool to lock the inference direction.
  7. While holding the Shift key, draw a circle, whose diameter will be the diameter of your inner tube, perpendicular to the first circle. This circle is the profile of the inner tube.
  8. Select the edge of the circle on the ground plane. This is your path.
  9. Select the Follow-Me tool.
  10. Click on the profile of the inner tube. An inner tube is created.
