Tube

The Tube command draws a closed cylinder with a concentric cylindrical hole.

Pick the center and radius of the base.
See the Circle command for option descriptions.
After drawing the base circle, pick the radius/diameter for the second tube wall.
Pick the end of the tube or type a height.

Command-line options
Direction constraint options	Direction constraints restrict the direction of the circle. None 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. The BothSides option demonstrated with the Line command.
WallThickness	Specifies the value for the distance between the inside and outside of the tube.
