Lesson 1A - Create MultiportSteps 1 to 11

When a wire connects to a part we are concerned not only with the physical connection but the logical connection as well. The connection list provides the identifier of electrical pin to be connected to so that id must be supplied by the connector for the wire to route successfully.

A multi-port provides the method to assign many identifiers under a single object. Each identifier may, optionally, have its own location.

Step 1	Open part file round_connector_unqualified.prt by choosing File->Open and double clicking on the part name.
Step 1A	Rotate the part so that the face of the cylinder with the holes in it is pointed towards you, out of the screen.
Step 2	Choose Application->Routing->Wiring from the Unigraphics NX Application Pull down.
Step 3	Choose the Qualify Part button in the Wiring Toolbar (far right end). ·         The Qualify Partdialog shows a structured tree list with all the possible object types that may be created.
Step 4	Highlight Multi under the Port branch using MB1. Holding down MB3 with the cursor over the Multi entry, choose NEW.·         The Multi Port dialog is displayed.
Step 4A	Enter the value 0.0 in the Engagement field.
Step 4B	Enter the value 1.0 in the Extension field.
Step 5	Select the outer circular edge of the cylinder on the front face of the connector to define the port origin.
Step 6	Select the second (middle) Selection Step icon (top of dialog).·         Selecting the second selection step icon accepts the origin point for the first selection step and moves you on to define the port alignment vector.·         The alignment vector, defined by the plane of the selected arc, is temporarily displayed.
Step 7	Choose OK again to accept the port alignment vector, or choose Cycle Direction if the alignment vector is not pointing out of the part, then choose OK.·         You are now in Selection Step 3, which is an optional step for defining a rotation vector. Choose OK once more to indicate there is no rotation vector and the Selection Steps are complete. The Multi Port is created.·         Since this is a Multi-Port, the Assign Terminals dialog is displayed.
Step 8	Choose the Generate Sequence button on the Assign Terminals dialog.
Step 9	In the Generate Sequential Names dialog, choose Method A, B, C.
Step 10	In the From and To fields, enter A and J respectively.
Step 11	Choose OK to generate the names.·         The Terminal IDs A through J are listed in the Terminal Names list of the Assign Terminaldialog.These names are, at this point, called virtual ports. They carry the logical pin information for the multi-port. Any number of virtual ports may be defined for a single multi-port.

Steps 12 to 17

NOTE: The next five steps show how to define terminal ports associated with this multi-port. Terminal ports are only necessary to do Create Terminals, which you may or may not be interested in. The multi-port, as defined at this point, contains all the information needed to route the harness bundle up to the connector and maintain the logical connection information.

Step 12	The dialog now lists Terminals A-J. Hold the cursor over A and, holding down MB1, drag it down so all terminal names are highlighted. Choose the Place Terminals button.·         The Place Terminaldialog is active to place terminal A.
Step 13	Select the circular edge of one of the small holes, at the bottom of the hole. Choose OK to accept the direction of the newly created terminal port.·         A terminal port, designated as terminal A, is created at the arc center.Repeat for remaining terminals, selecting a different hole for each.·         Terminal ports are created for each terminal. This is shown in the image at the end of this lesson.
Step 14	Choose OK to get back to the Qualify Part dialog. Notice that the port you created now appears in the tree list. If you expand this entry, by clicking on the plus sign beside it, you see all the terminals you generated.
Step 15	With the cursor over your new port in the tree list, press MB3 and choose the Characteristics option.
Step 16	Choose the characteristic named CUT_BACK_LENGTH. ·         The characteristic title is placed into the Title field and the current value, 0.0, is placed in the Value field.
Step 17	Enter the value 3.0 into the Value field and choose OK.This port now has a cut back length of 3.0. This value is used for the Create Terminals function, covered in a later lesson.

Step 1	Open part file straight_connector_unqualified.prt and start the Wiring application.
Step 2	Choose the Qualify Part button in the Routing Toolbar.

Steps 3 to 12

Step 3	Using MB1, highlight Fitting, under Ports, and then use MB3 to choose NEW.·         The Fitting Port dialog displays.
Step 4	Choose Two Lines from the Filter pull down menu.·         Two Lines lets you choose two lines, from which the system defines an area and determines the center point to use as the port origin.
Step 5	Choose two parallel lines from the side edges of the hole in middle of the top face of the connector. A temporary point is displayed indicating the origin for the port.
Step 6	Go to the second of the three selection steps of Qualify Part by choosing the middle button at the top of the dialog.·         This step defines the Port Alignment Vector.·         A temporary vector is displayed showing a proposed alignment vector for the new port.
Step 7	If the vector is pointing down, into the connector, choose the Cycle Direction button to reverse it.
Step 8	Choose the third selection step by choosing the third button at the top of the dialog.·         This step defines the Port Rotation Vector.
Step 9	Use the Filter pull down menu to choose Vector.
Step 10	Use the Vector pull down menu to choose the YC axis to define the direction of the rotation vector.
Step 11	Enter the value 360 into the Clocking Angle entry.·         A clocking angle of 360 means that a component attached to this port can be rotated only in increments of 360. There is, therefore, only one way this connector can be placed into a socket (provided the socket has a port with a rotation vector and itself has a clocking angle of 360).
Step 12	Choose OK.The port is created as shown below.

Qualify Part

(Wiring Application)

Overview

Qualify Part is used to add information to a component part by all Routing applications. A description of the use of this tool is in the Routing Help. This section presents considerations specific to Wiring.

Qualify Part the addition of Routing specific intelligence to a part file. This intelligence dictates how that part places into a routing assembly, how it relates to other parts in the routing assembly, and how it behaves during routing operations. Qualify Part provides the exclusive interface for creating Routing specific objects in a part file that carry this intelligence. These objects are ports, anchors, terminals, built-in paths and cross section curves.

Using Qualify Part for Wiring

For Wiring, qualifying a part includes creating ports and assigning characteristics within the part in order to manage the electrical connectivity information as well as mechanical connectivity information.

Wiring uses Multiports, with Virtual Ports and Terminal Ports, to carry electrical connectivity information for the component. These ports create in Qualify Part. A Multiport allows you to define a single physical location point to represent and associate many logical connections. Establish virtual Ports by associating Unique IDs to a Multiport, representing logical connections. The Multiport provides the physical connection location of a virtual port. A virtual port becomes a terminal port when a separate physical location point is established.

The logical association between the Multiport and a Terminal Port, with the Terminal Port being dependent on its Multiport, remains intact and allows Wiring to automate the process of creating terminal wires throUGh Create Terminals. Terminal Ports define by reference to an instance array, both circular and rectangular. Terminal ports defined by instance arrays are useful when qualifying connectors with many pins.

Below are descriptions of Routing specific objects as they relate to the wiring application.

Anchors	Use anchors as physical connection location points when adding the device to the assembly using Routing's Place Part function. You can create anchors at obvious mounting points such as the center of a connector or the corner of a mating face in order to use Place Part to add the component to the assembly. Electrical components may be added using standard Assemblies tools, in which case Anchors are not needed.
Ports	Use ports to define a single, physical connection location points. For Wiring, we recommend that standard ports be used to identify connections between devices and connectors. When routing to standard ports, you must create separate paths to each port individually to establish connectivity. For that reason, we do not recommend using standard ports to represent terminal pins.
Multiports	A Multiport creates to multiple logical connections using a single connection object. The Multiport represents a collection of logical connections by maintaining a list of unique identifiers. You only need to create one path to establish all the logical connectivity to the unique identifiers (pins) of the component (typically a connector).
Virtual Ports	If you do not define a Terminal Port for a unique ID included in the Multiport list, then it is considered a Virtual Port, since it has no physical definition. Virtual Ports enable a logical connection to the component defined by the Multiport without requiring a separate physical location for each connection.
Terminal Ports	Terminal Ports define a physical point of connection for one unique ID included in a Multiport terminal list. You must define Terminal Ports to take advantage of the Create Terminals feature.
