Ultra Fast Way to Draw Primitive Solids

... with Adobe Illustrator.


Cylinder
  1. Select the bottom anchor, and press Ctrl-X.
  2. Press Ctrl-F, and drag it downward with Shift key pressed.
  3. Select the right side anchors and press Ctrl-J. Do the same for the left side.
  4. Press Ctrl-F again.

Box
  1. Draw a rectangle.
  2. Drag the right side segment. Then select whole shape and press Ctrl-C.
    Then press Ctrl-F twice.
  3. Drag the left side segment.
  4. Drag the lower side segment.
  5. Select marked anchors, then drag one anchor to be snapped.
  6. Colorize as you prefer.

Cone
  1. Draw an oval.
  2. Drag with Alt key pressed to duplicate. Snap the lower anchor to the center.
  3. Drag the upper box of the bounding box with Shift key pressed, so that the shape is enlarged with keeping the aspect ratio.
  4. Draw a path with Pen tool to connect the intersection points and the upper anchor.
    -- These 2 lines are exactly tangential to the oval. (To be accurate, these are almost tangential because the oval is an approximated one by the bezier curve.)
  5. Unite with pathfinder if it needs.

  2. lovely explanation!
    there was a time I used to teach a similar way to draw in FH9. Some problems came up while drawing a truncated cone (ie. like a simple plastic cup), because of lack of precision to get the tangent point between ellipses. anyway, students got the idea, all passed the final exam.
