Layout preferences define—by connection type and shape—the default parts for a domain (duct, pipe, cable tray, or conduit). The default parts are the segments and fittings to use by default during layout. For more information about the Duct Layout Preferences dialog box, see Configuring Duct Layout Preferences.
When you are creating custom parts, you can retrieve the sizes defined for the connector parameters of the default segments and insert them into the custom parts. For example, suppose you have a custom square-neck diffuser with a duct connector that is rectangular and banded. To represent the width and height of the duct connector, the diffuser has 2 size parameters named RW1 and RH1. To quickly insert a list of sizes into these parameters, you can retrieve the sizes in the RW1 and RH1 connector parameters for the segment specified as the default during layout of rectangular, banded duct.
Inserting the sizes of the default segments into your custom parts is particularly useful when the list of sizes that you need is long and closely matches the values for the corresponding default segment. Be aware that the software replaces any existing values with the inserted values. After you insert the values, you can add and remove individual sizes as needed.
To insert the connector sizes of a default segment into a part
Alternatively, you can right-click a value, and click Default.
For pipe connectors only, you must select a pipe fitting because pipe fittings, not pipe segments, have connection types.
The software inserts the values of the connector parameter in the default segment into the selected connector parameter in the custom part.
