1. A method for determining and drawing a flexible drop for connecting a sprinkler head to a sprinkler system pipe within a CAD drawing of a sprinkler system, comprising the steps of:

  • receiving from a user a location for the sprinkler head;

    receiving from the user one or more parameters for determining the flexible drop, the one or more parameters including a connection type between the sprinkler head and the sprinkler system pipe, the connection type including a flexible drop configuration and a hard-pipe-to-flexible-drop configuration;

    determining a connection point on the sprinkler system pipe for connecting the flexible drop based on the location for the sprinkler head, a location for the sprinkler system pipe, and the one or more parameters;

    if the connection type is the flexible drop configuration, drawing the flexible drop within the CAD drawing from the connection point to the location for the sprinkler head; and

    if the connection type is the hard-pipe-to-flexible-drop configuration, drawing a hard pipe within the CAD drawing from the connection point to a pipe-drop-to-sprinkler distance, and drawing the flexible drop within the CAD drawing from the pipe-drop-to-sprinkler distance to the location for the sprinkler head.
