Safety posts are generally placed at the ends of bays and prevent vehicles from accidentally hitting pedestrians.
Click on the Safety Posts tab.
The Post diameter is the diameter of the safety post.
The Width is the width of the safety barrier, i.e. the distance measured in the direction of the bay width.
The Length is the length of the safety barrier, i.e. the distance measured in the direction of the bay length.
The Offset is the distance from the center of the safety post to the end of the bay.
Select Offset from curb to measure the offset from the curb instead of the end of the bay. Note this will only affect angled bays.
Click the Line Style button to modify the Color, Line type and Line weight in the Attributes dialog.
