Click a Rectangular Duct item in the navigation tree to see the = options available for that item.
Using the 2way Transition as an example, this section will explain some = of the options available. Understanding the options for one item will help = you better set up the others.
Width 2 and Height 2 =E2=80=93 set the default reducing= amount
Straight 1 and Straight 2 =E2=80=93 inches of straight = after the transition
Length 1 =E2=80=93 enter SMACNA to use the 15 degree ru= le or a formula
Top and Left Offsets =E2=80=93 default amount to offset= the duct item
Minimum and Maximum Lengths =E2=80=93 set the limits fo= r short and long transitions
Length Adjustment
The pressure file handles the standard fabrication of an item based on a= n average or base length. If that length is adjusted by the user in takeoff= , apply an adjustment.
Base Length =E2=80=93 average length for a transition t= hrough the center line length of the item.
Every # of Inches or % of change =E2=80=93 enter a numb= er to state the length adjustment threshold or a number with the percentage= symbol to have the adjustment based of a percentage of growth
Min Fab Labor =E2=80=93 since the labor can be reduced,= set a minimum fab labor for the item if desired.
Add % to Fab =E2=80=93 the percentage the item fabricat= ion labor (pressure file labor) should be increased.
Subtract % from Fab =E2=80=93 the percentage the item f= abrication labor (pressure file labor) should be decreased.
