Creating a Path Reservation

atarget.gif (1372 bytes) This task shows you how to create a path reservation on an area.
When you route, by default the run is created on the XY (Z=0) plane. If you want to route a run on a specific surface or another plane, then you need to place the compass on the plane or surface on which you want to create the run. In the image below, if the compass had not been placed on the surface, routing would take place at the XY plane. If the user wants to route on the surface of the object, he has to place the compass on it (as shown). The run will be created on the base plane of the compass, as shown below.

See Making an Element Active.

  2. Select the Path Reservation button .

The Path Reservation dialog box displays.

3. Define the type of path reservation you want to create.

4. Define the routing mode for the path reservation:






Branch at Center: see Branching a Path Reservation

In addition, if you place the compass on an object the Use Compass Origin button will display. If you click the button and start to route the route will start from the compass origin. If you are in the middle of routing, the compass origin will serve as a routing point.

Click one of the Select Mode buttons - the default is No Filter. The Select Mode buttons allow you to define where you can start routing from.

No Filter: No filters are applied and you can route from any routable object or in space.

In Space: Routing will be in space. This is useful when you have a large object in the background, such as a ship structure, and you want to be able to route in space. You must select this option when you are routing in cache mode and you want to route in space with an object in the background. When you are in design mode you do not need to select this option. You can also select the option Allow selection of objects in cache mode during routing. If the option (Tools - Options - Equipment & Systems - Design Criteria) is un-selected then you will not need to click the In Space button.

Only Part Connectors: Select this to be able to route from part or equipment connectors only.

Select part to display connector list: This button allows you to use a dialog box to select the connector on which to place a part, and is useful in busy documents. Click this button if you want to select the connector on which to place your part by using a dialog box, instead of selecting the connector in the viewer. With your document open, select the part you want to place, click the Select part to display connector list button and choose the part on which you want to place your part. A Selected Part dialog box will display, showing all the connectors on your selected part. The selected connector will be highlighted, and will be orange in the viewer. Select the connector on which you want to place your part and click OK.

Import Node Points: This allows you to route using predefined node points. See Routing with Defined Nodes for more information.

5. To define Section parameters, do the following:

a. Click the Section type button to define the section type of the run.

The Section dialog box is displayed.

b. Define the section type and the corresponding parameters for each of them:

No Section


  • Set Point
  • Envelope Height
  • Envelope width
  • Display
  • Nominal size


  • Set Point  
  • Envelope diameter
  • Nominal size
  • Display

Flat Oval.

  • Set Point
  • Envelope Height
  • Envelope Width
  • Nominal size
  • Display

Radius Corner: Enter or select the:

  • Set Point
  • Envelope Height
  • Envelope Width
  • Radius Corner
  • Nominal size
  • Display
The Display buttons allow you to select a display mode of Line/Curve, Solid or Flat. 

Click the Display Centerline button to show the centerline of the run. This will appear as a dashed yellow line. In addition, a blue line will appear to display the Set Point setting. This feature works in the Line/Curve, Solid and Flat display modes.

Instead of entering the type of path reservation, the set point and the height, width or diameter in the Section dialog box,  you can select an existing path reservation in your document. Once you select the path reservation the Section dialog box will display the same values as the one you selected. To select, click on the Path Reservation button and then click the left mouse button once on the path reservation whose values you want as the default. Make sure the entire path reservation is selected, and not just one segment or node. It will be easier to select the path reservation in the specifications tree.

6. Select OK on the Section dialog box.
7. Optional. Key in a value for the turn radius.
8. Click in the drawing to define the routing points.
9. Double-click the last point to stop routing.
10. Click on the Close Loop symbol closedloop.gif (185 bytes) that shows at the beginning of the routable if you want to create a closed loop routable. In a closed loop routable the ends of the routable are joined.
