A Drop/Run accounts for additional material needed when taking off objects such as plumbing fixtures and electrical items. The Drop/Run accounts for the vertical run necessary to reach the intended outlet, sink, or fixture.
Applying a Default Drop/Run Value to Linear Objects
Linear Conditions can be setup to apply a specific Drop/Run value to every segment drawn. If each (or most) segments requires the same Drop/Run value, enter a value in "Add Length" and On-Screen Takeoff will add a drop-run box to each object with the default value inserted.
Even though this default value is entered into the Drop/Run box automatically, you can always change or deleted the value after
drawing the object. Entering a default "Add Length" value
after performing
takeoff does not update existing
takeoff objects, just objects you draw after changing the setting.
Open the Conditions Properties dialog and select the Advanced tab
Place a check in the box next to "Drop/Run" in the Measurement field
Add the desired Drop/Run length in the "Add Length" box (in the example, a 1'6" drop/run)
Now, every takeoff object drawn with this Condition will show a A "Drop/Run" box with a value of 1'6". You can always change the value on a segment-by-segment basis. Just click on an object's Drop/Run box and enter a new value - only that single takeoff object will be affected.
To change a Drop/Run for all future takeoff objects, edit the Condition Properties and change the drop/run value. Remember, existing objects will not be affected by changing the default value for Drop/Run, however, if you uncheck the "Drop/Run" option in Condition Properties, you will remove all Drop-Runs previously applied (if you re-enable the option, previously set Drop/Runs will be restored).
Entering a Manual Drop/Run Value per Segment
To add a Drop/Run value to specific segments, or to apply a different Drop/Run value for each segment, setup the Condition to add the Drop/Run box but leave the "Add Length" box blank.
Open the Condition Properties dialog and select the Advanced tab
Place a check in the box next to "Drop/Run" in the Measurement field
Leave the "Add Length" field empty
Now, when you draw segments with the Drop/Run box checked and no value set, a small box appears next to every segment of that Condition
Select the value box and enter any value for each segment...
