Steps

  1. Pick the center and radius of the base.
    See the Circle command for option descriptions.

  3. Pick the end of the tube or type a height.

Command-line options

-Direction constraint options: Direction constraints restrict the direction of the circle.

  • Nonce: The center can be anywhere in 3-D space.
    • Pick the second point anywhere using elevator mode, object snaps or other modeling aids.
  • Vertical: Draws an object perpendicular to the construction plane.
    • Pick the center and a radius or diameter.
  • AroundCurve: Draws a circle perpendicular to a curve.
    • Select a curve and pick the center of the circle on the curve and a radius or diameter.

-BothSides: Draws the object on both sides of the start point, creating the object twice as long as you indicate.

-WallThickness: Specifies the value for the distance between the inside and outside of the tube.
