Creation Method rollout
Edge—Draws the object from edge to edge. You
can change the center location by moving the
mouse.
Center—Draws the object from the center out.
Parameters rollout
Radius—Sets the radius of the oil tank.
Height—Sets the dimension along the cen tral
axis. Negative values create the oil tank below the
construction plane.
Cap He ight—Sets the height of the convex caps.
The minimum value is 2.5% of the Radius setting.
