AutoCAD and Its Applications—Advanced
In Figure 8-17A, the bottom shelf has been created as an extruded solid from an
ellipse. The shelf is .375″ thick and is centered on the UCS origin. The underside of
the shelf rests on the XY plane. A second ellipse is drawn on the XY plane and rests
on the underside of the shelf. This ellipse serves as the path for the 3D path array.
A construction cylinder has also been created with its base resting on the XY plane.
The construction cylinder is 2″ in diameter and 2″ in height, the dimensions of the
table feet. The construction cylinder is the item to be arrayed. During the operation,
the base point of the array is specified as the top center point of the construction fi
cylinder. This aligns the top of the cylinder with the start of the path. Since the path
is an ellipse, AutoCAD defi the start of the path as one of the quadrant points on fines
the major axis. When the base point is selected, the cylinder is then aligned with the
quadrant point. This is a sufficient start point for the array. fi
