Cylinder

The Cylinder command draws an Extrusion cylinder.

Command-line options

• DirectionConstraint: Direction constraints restrict the direction of the cylinder.

  1.None: Pick or type a number to set the height.

  2.Vertical: Creates a cylinder perpendicular to the construction plane

  3.AroundCurve: Draws the base circle perpendiculart to the picked point on a curve. The center line of the cylinder will be tangent to the curve.

• Solid: Caps the top and bottom openings or leave them open.

• Radius: Draw the base circle by picking the center point and a radius point.

• 2Point: Draws the base circle from two opposite points.

• 3Point: Draws the base circle through three points.

• Tangent: Draws the base circle tangent to one, two, or three curves.

• FitPoints: Draws the base circle by fitting to selected points, control points, or mesh vertices.

• BothSides: Creates a cylinder symmetrical across the base circle. The height of the cylinder is twice as long as you specify.

Steps

1. Draw the base circle.

2. Pick a location or type a number to set the height.

   The DirectionConstraint options define the positive height differently.
