Creating a Run Using a Schematic

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

Beginning Release 15, 3-D 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.

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 must be in the appropriate workbench.

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

The left side of the Schematic Browser  dialog box (the tree section) displays the 2-D/3-D integration status of the listed objects. The integration status updates automatically when the dialog box displays.

A green checkmark indicates a schematic associated with a 3-D object.

A red X indicates a schematic not associated with a 3-D object.

You can manually update the 2-D/3-D integration status of the objects. However, you must set your Tools - Options as follows:

From the menu bar, select Tools - Options - Equipment and Systems. On the Design Criteria tab, uncheck the Automatic 2D/3D Integration Status Check checkbox.

Now when you display the Schematic Browser, the integration status does not update, and you see yellow question marks in the tree section beside certain objects.

You also see the Update Integration Status button at the bottom of the Schematic Browser.

  To update the 2-D/3-D integration status manually:
  • Select a specific object in the tree section (displaying a yellow question mark). The integration status of the selected object updates. (It now displays a green checkmark.)
  • Click the Update Integration Status button. The integration status of all the objects displayed in the tree section updates. (All the objects displaying yellow question marks now display green checkmarks.)
2. 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 from the drop down list. 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.
 

FOR HVAC DESIGN ONLY

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 display 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.
