The Properties command will allow you to determine the properties of a selected symbol and in some cases, make changes to the property settings. For example, you can change a selected piece of equipment such as a sprinkler from one manufacturer and type to another.
The properties differ from one object to another. Most entities display basic properties such as the X and Y locations on the drawing screen. Other more specialty properties exist such as the Override Label Point that will allow you to manually move pipe sizing labels on the screen.
