Creating a Run Using a Schematic

This task shows how to create a run using a schematic drawing.

You must follow the parts placement order described in Schematic Driven Design. You must also set the Schematic Driven flag described in the same section.

Beginning Release 15, 3D versions of runs must be 'associated' with the corresponding schematic, if you want to do schematic driven parts placement on a run. Runs will automatically be associated if you create them in Release 15 using a schematic. Runs that are not associated with the corresponding schematic must be associated by you - if you want schematic driven parts placement.  See Analyzing Schematic Driven Design to learn how to do this. As a visual aid, runs that are associated display a check mark in the specifications tree . Runs that are not associated display an X .

You can use a schematic with a branched run, or a run that is not connected to other objects.

In order to place equipment you must be in the Equipment Arrangement workbench. To create a run and place parts you should be in the appropriate workbench.

1. Click the Route Run button . The Schematic Browser and Run dialog boxes display.

Note: Some of the buttons display after you have selected a run.


In the schematic displayed in the Schematic Browser, click on the run you want to create. The 3-D viewer will show a possible route.

The function can distinguish the schematic objects (equipment and nozzles only) between which the run existed, and select their 3-D equivalents to route between.

3. If you want the application to show you possible paths between two objects, then select your beginning and end points and click the Display Alternate Path button . The first click displays a field showing the number of possible paths: . Subsequent clicks show the actual paths.
  4. Select From/To or Logical Line by clicking on the down arrow. This affects the display of objects in the specifications tree, and the Route Through Hangers option (see below). If you select Logical Line only the logical line will display in the tree. If you select From/To then the objects routed from and to will also display.
5. Once you have a route you want to accept, click OK or the Create the Run button and the run will be created. If you click the button you can select another run. If you click OK you will exit the command.

If you named the connectors when you created them (in both the schematic and 3-D applications) then the run will be created between connectors that have the same name as in the schematic.

  6. Click the User Defined Path button if you want to define a route yourself, such as through one or more hangers. To route though hangers, click the button and then select the hangers you want to route through. The User Defined Path button is only available when the two points you want to route between exist in the 3D window.
The Run dialog box displays other options. These are regular Routing options that are explained in Routing a Run, and allow you to route as you would normally. The Reframe button allows you to zoom in on an object in the 3-D viewer.


The Ductulator button displays in the Type field if the 2D segment you select has the Equivalent Diameter property defined and valuated.

The Ductulator is a tool for calculating the area of a rectangular or square duct that is equivalent to the diameter of a given round duct. It enables you to place the correct-sized duct. Click the Ductulator button to being up the Duct Size Computation dialog box.

The diameter of the line you clicked on is displayed in the Equivalent Diam field. Select a value for the Inside Height property to obtain a value for Inside Width. Or select a value for Inside Width to obtain Inside Height. You should select by clicking on the down arrow next to each field - the values displayed are obtained from your catalog. The Exact Result field displays the exactly computed result - instead of this figure the application will select a size that is available to you. The Aspect Ratio field displays the aspect ratio of the two values.
