Replacing a Component

atarget.gif (1372 bytes) This task shows you how to replace one component with another in a schematic diagram. It uses piping components to explain the task, but the procedure is the same for other types of components.

When replacing components in a diagram, certain conditions for, and consequences of, replacement must be taken into consideration.

Connections - Using the Replace Component feature will connect all compatible connectors of the new component with the objects originally connected to the old component based on compatibility and proximity criteria as follows:

  • For each compatible connector on the new component, the closest compatible connector of one of the objects originally connected to the old component will be connected until all the connectors on the new component have been used.

Attributes - All attributes on the old component will be retained unless the new component is a reference component that has its attributes protected on the Attributes Usage List.

Component Instance Name - A new component name will be generated in the specifications tree for the new component.

Annotation Links - All annotation links of the old component will be lost. The replace feature will not attempt to copy them to the new component.

Graphical Representation - The primary graphical representation of the new component will be used.

Flow - Flow reality, the same as that used in component placement, will be checked as part of the compatibility checking (above). 

Orientation

  • For unconnected component - applies the orientation matrix of the old component on the new component.
  • For connected component - applies the orientation matrix of the old component to the new component and finds the closest connector (in distance) on one of the originally connected objects. Performs a component placement on the connector found.

  The Catalog Browser displays. 

2. Select the component from the Catalog Browser.  In this case, a blocking valve is replaced with a metering valve.
