Changing a Part to Match Another Part
Use this procedure to change an MvPart to match another MvPart in the drawing. You can change an MvPart
of one type to match an MvPart of another type. For example, you can change a valve to a pump.
1 Select the MvPart you want to change.
2 Click Equipment tab
➤
Modify panel
➤
Modify Equipment .
3 In the Multi-view Part Modify dialog, click (Match) in the lower-left corner.
4 In the drawing, select the MvPart you want to match.
5 Press enter to match both the part and the elevation.
In the Modify Multi-view Part dialog, you can also specify a different size for Part Size Name, or
a different value for Elevation.
6 In the Modify Multi-view Part dialog, click Close.
To change the size of the MvPart, see Modifying HVAC Parts on page 231.
Modifying the Flow Value Assigned to a Part
Use this procedure to change or assign a flow value for devices such as fans, VAV boxes, and ceiling diffusers.
1 Select the part you want to modify.
2 Click Equipment tab
➤
Modify panel
➤
Modify Equipment .
3 In the Multi-view Part Modify dialog, click the Flow tab.
4 Specify a new value for Flow.
Modifying the System Assigned to a Part Connection
Use this procedure to change the system assigned to an MvPart connector. When you add an MvPart to a
drawing, there are no systems assigned to its connectors. If you connect a duct run to an MvPart connector,
the connector inherits the system setting from the connecting duct object.
You can specify the system for MvPart connectors. Then, if you use the add grip to begin drawing duct runs
directly from the MvPart, the system is already specified for the new run.
If you change the system for an MvPart connector that is connected to a duct run, the system for the duct
run changes to match that of the MvPart connector.
1 In the drawing, select the MvPart you want to modify.
2 Click Equipment tab
➤
Modify panel
➤
Equipment Properties .
3 In the Multi-view Part Properties dialog, click the Systems tab.
4 In the System column, click in the field for the connector you want to specify.
5 Select a system from the drop-down list.
Modifying Duct
After adding ductwork, you can modify the segments and runs based on design changes or layout
requirements. You can move single objects or groups of connected objects. You can change the system,
elevation, shape, size, and part type of a duct segment. You can also use the duct system size calculator and
instant sizing tool to recalculate duct sizes as you modify and refine your systems. You can also change a
duct fitting in a run, the position of an off-center fitting, or a custom fitting.
