Object Templates

Object Templates allow parts of the network design process to be automated with pre-defined structures.

  1. Continue working on your previous file or open CAD Import.iddx, but save it to a file called Creating a Network.iddx.

    Note that you should periodically save your work throughout the exercises.
  2. Turn off the Surface and Deluge layers in the Tree View.
  3. Create an object by going to File > Object Templates.

    Templates can be made for any object, but for this example, we will only use a Manhole template.

  4.  Select Junctions then click the + icon to add a new manhole.

  5. InfoDrainage will prompt us for a name to save this template (use ID_Metric_Intro_Tutorial.idtx). Click Save.
  6. Enter a name to identify this manhole (use Manhole Template) and enter in a Depth of 2 m.

  7. The other values are left as zero as they can be extracted from the CAD and Surface Data. Click the Cross button to exit out of the Template form. Data is automatically saved. 

Drawing the Network

  1. Select the Snap option in the Plan ribbon. This precisely attaches paths to drawings depicted from the CAD data.

  2. Go to the Build ribbon and select Add Network. Select the Manhole Template template, which we have just created, using the drop-down menu immediately to the right of the Add Network button.

  3. Start by left-clicking near the houses in the South West of the catchment and continue to connect the manholes downstream, as seen in the following image. Finish the path by pressing the Esc key.

    Tip – Use the mouse wheel to zoom in and out, to accurately position the manholes. Hold down the mouse wheel to pan.

  4. Click on the Select Tool in the Toolbox, otherwise more manhole will be created when you click on the Plan view.

  5. The default font size makes the view difficult to distinguish so it is useful to change the labels to make it easier to read. Right-click on the Plan and open the Display Settings form to change this. Select the Plan tab and enter 4 m as the Text Height then close the form.

  6. Click the Connections button in the Build ribbon, or double-click on Connections in the Tree View, and rename “Pipe(x)” to “Px" as shown below. Click OK.

  7. To rename the manholes, select the Tables button from the Build ribbon. Select the Junctions tab in the Tables dialog, click the little junctions icon  then expand and turn on all the tick boxes. It may then be necessary to close the Table and open it again. Then enter the new names below. Click OK to apply the changes.

  8. Plan colours can be changed for better visibility. Right-click on the Plan view and select Display Settings. It is also possible to lock layers when you are happy with their location.

  9. Next, we will add the other part of the branch line. Using the Add Network button on the Build ribbon, add in a branch line from the West of the catchment to MH8. Press the Esc key to connect the new branch to MH8.
  10. Open the Connections again and renumber the new pipes from P14 up to P18.
  11. Open the Tables and renumber the new manholes from MH15 up to MH19.

Catchment Areas

The catchment areas can now be defined, either by manually digitising them or importing them. In this example, they will be imported.

  1. From the Import ribbon, select Inflows (From CAD).

  2. Locate the .dwg file used previously and then click Next.

  3. Click Deselect All then turn on the Areas layer and click Next again.

  4. You can leave the default Catchment Area template selected and click Finish.

  5. The areas will automatically be assigned to the upstream of each branch. To move the icon, Click with the left mouse button and hold down the Shift key on the keyboard to drag it separately to the area Outline. The Catchment Areas can be renamed if needed. 

  6. Save the file.
