1. |
To select the component in your
document whose attribute is to be propagated, right click the object in the
specifications tree and select Properties from the menu. Alternatively,
select the object and click Edit - Properties. |
|
2. |
In the example below, the Properties dialog
box is displayed with the HVAC tab open and the Propagate button visible.
In this case, we have a volume damper placed on a 40 inch line.
|
|
3. |
In the Properties dialog box, change the value
for Equivalent Diameter to 48 in. Click the Propagate button.
The Attribute to Propagate dialog box opens showing the attributes that can
be propagated. Click on Equivalent Diameter.
The objects in the propagate path for the attribute 'Equivalent
Diameter' will highlight. If a different attribute is then selected, the
new path will highlight. |
|
4. |
Click OK in the Attribute to
Propagate dialog box to return to the Properties dialog box. Click
Apply or OK. The equivalent diameter of the volume damper
will be overridden to 48 inches and all objects in the network with a
'equivalent diameter' attribute will be changed to 48 in. See Rules, below,
for requirements and limitations on propagating an attribute. |

Rules
This function allows you to propagate a size value over a
network path. Propagation may occur in all directions from the propagating
object with the following exceptions which limit the extent of the
"network":
-
Objects of a different discipline than the propagating
object.
-
Objects with no nominal size, or equivalent size
attribute.
-
End of a network path (i.e., no connectivity).
-
Off-sheet connectors.
-
Branch to Main Route.
-
Main Route to Branch.
-
Object in a different logical line (Line ID).
-
Nozzles.
-
Reducers - one side is affected.
-
Switching Valve (3-way) or a Switching Valve Function
(4-way).
