Import CAD outlines for Inflow Areas

  1. Begin by opening the ID_US_Introduction_Project_Ch1.iddx file.

    Note that the Existing site conditions have already been imported – don’t worry, importing and adjusting Inflow Areas will be covered in this tutorial!
  2. Catchment extents have already been delineated within CAD so we can Import these into InfoDrainage as Inflow Areas. 
    1. Right-click the Inflows layer and select Import from CAD.


    2. Click Select and then locate Inflow Areas_Developed.dwg and then click Open.


  3. Click Next twice in the Load CAD Wizard.


  4. Click the Comm Inflow Area Template on the Select Template screen and then select Finish. This Template represents commercial land use characteristics, which we can further modify later in the tutorial.



  5. Double-click or right-click and select Edit on Comm (1) in order to see the Inflow Area characteristics, which are applied based on the outline extents for that element and the details saved under the Comm Template. Click OK to close the dialog.


Import Pipe Network from GIS

  1. Now that the Inflow Areas are set, right-click the Connection layer and select Import from GIS, or select Connections within the From GIS group on the Import ribbon.
     


  1. On the Import dialog, use the Select button to select the Pipe Network.shp file, and then click Next.


  2. The GIS file will be shown on the second Import step, as the units are set to feet by default, select Next to continue.


  3. This step allows you to select which Connection Template will be used if any missing attribute data exists, in this case select Standard Pipe for the Template. Click Next.


  4. Similarly, select Standard MH for the default Junction Template to be used as the default Junction type when the imported connections join. Select Next to continue.


  5. We can now map pertinent variables from the GIS file attribute list to the associated input types within InfoDrainage. These can individually be dragged from one side to another or a mapped list can be loaded (if previously saved) by using Load, then select GIS pipenetwork mapping.xppmx and select Open.



  6. Once these fields are mapped, select Import, then click OK on the import summary dialog.



  7. The model now contains all Inflow Area catchments and the Pipe Network. You may wish to change the Display Settings to make things easier to read. Labels can be turned on and off in the Layers tab and Text Height and (Max) Icon Height on the Plan tab.


Update Characteristics Using TABLES

In addition to importing from several formats, it is easy to make updates to a system using TABLES. We will use TABLES to make updates to runoff characteristic info for Inflow Areas.

  1. Open TABLES by selecting the Tables option within the Build ribbon or double-click the Tables layer within the Tree View.


  2. Expand the Inflow tree and select the items listed below: Area, Runoff Method, as well as Area, Pervious Curve Number, Percentage Impervious and Composite Curve Number, which are found within the SCS branch. This same information can be viewed for individual Inflow Areas by editing the given area in the Profile view.


  3. We can update the Percentage Impervious (%) field for the Inflow Areas shown below to better reflect the proposed parking plan.


  4. Once these values are updated, click OK to accept the changes and close TABLES.
