Thanks.
Odd thing though, the objects only show up when I select All Libraries instead of a AC 12 Library.
There are two objects:
a) Parking Place 12. When I try to widen the default stall width of 8'-2" I end up with only one 'line'. Not sure how to increase the number of parking stalls.
b)Parking Place Polyline 12. This offer little more flexibility. However it has its own set of quirks. If I increase the number of parking stalls the HC symbol disappears. Unable to remove or modify this object so it appears as open end stalls stall instead of rectangular boxes in 3D view.
Unless I am overlooking some parametric controls I find these objects 'clunky' to work with.
