Overview

This lesson shows how to route wires according to the imported connection list and component list (previous lessons). A wire can be routed provided that the components that the wire runs from and to have had their identifiers assigned, that those components have ports with the correct pin ID's defined, and that there exists a path between the ports of the components.

There are two methods available to route wires. AutoRoute automatically finds the path and assigns the wire to the segments of the path found. If there is more than one possible path, AutoRoute uses the shortest path. If there are two shortest paths with identical lengths, an Ambiguous Path error is generated. Manual Route identifies all possible paths available to route a wire and allows you to choose which one to use.

Lesson 7A - AutoRoute

You may begin where you left off in the last lesson or, if you're not confident of your work, you may open the assembly part file named 7-tutorial.prt.

Step 1	Open the Connection List View of the Route List Navigator. Select all entries of the connection list.
Step 2	Confirm the active display format is Full (Route List->Properties).
Step 3	Use the MB3 pop up menu to choose AutoRoute. The system attempts to find a path for each wire selected in the connection list. If a path is found, then each segment making up that path is assigned that wire. The bundle solids associated to those segments are updated to include the new wire (increased diameter). The process does take some time - watch the status line for progress reports. 8 B  o6 v) N; P- f& r

NOTE: If any of the selected wires cannot be routed, the information window is displayed showing the status of each wire and, if it failed to be routed, the reason why. In this basic tutorial all wires are routed successfully so no Status Report is generated.

You might unroute all the wires and then unassign one of the connectors (using the Component List View).  Then try Auto-Routing the wires again and the Auto-Route Status Report will be generated. For any wire leading to or from the component you unassigned, the status will say the component was not found.

Lesson 7B - Manual Route

The AutoRoute function finds the shortest path of segments between the From and To locations for the wires. This may not be the only path for a wire. You can use the Manual Route function to select a specific path from a set of possible paths.

Step 1	Choose the 6th Connection List entry with Wire ID C6.
Step 2	In the MB3 pop up menu, choose DISPLAY. A straight line is drawn in the graphics window between the From Device/Connector/Pin and the To Device/Connector/Pin. This verifies that the From and To device/connector/pins have been found. It does not indicate that any paths of segments exist between them. However, because this wire is routed, the segments and bundles for this connection are highlighted. 2 Z6 r- j" ^; ^7 d% t! d8 T
Step 3	Choose the Manual Route from the MB3 pop up with C6 selected. The Path Confirmation dialog is displayed.
Step 4	In the Path Confirmation dialog, choose Next Path to cycle through the possible paths available (or just keep clicking MB1).
Step 5	Choose Accept or OK for one of the routes. The Wired field now shows M, meaning it is manually routed. The green check mark at the beginning of the record indicates this as well.
