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 r adius of the oil tank.
Height—Sets the dimension along the central
axis. Negative values create the oil tank below the
construction plane.
