Agility Course Master lets you add any number and sizes of round and rectangular "Unusable Areas" in your Place(s) to show you the location of poles, posts, walls, etc.

You only need to define these Unusable Areas once in each Place and whenever you Layout a Map in that Place you will see the obstructions so you can rotate, and adjust the Map to work around them.
