SWMM4 Import Dialog

The SWMM4 Import Dialog is used when Importing SWMM4 Network Data.

The dialog is displayed when Import | Model | from SWMM4 text file is selected from the Network menu.

  1. Enter the path to the text file you want to import in the Network (DAT) box, or use the browse button to select a file from a Windows File Open dialog. (SWMM4 text files traditionally have the extension .DAT, but this is not mandatory).
  2. SWMM4 uses the Manning equation to represent roughness. In InfoWorks, Manning values can be represented as either M = 1 / n or n. Use the Select Network Roughness Type radio buttons to select your preference.
  3. Set the network system type to an appropriate value using the System Type combo box.
  4. Click OK to continue the import. The OK button is only enabled if you enter the name of an existing text file.

An import log will be displayed with any conversion errors or warnings.

For details of the SWMM4 data blocks imported and conversions made by the importer, see the SWMM4 Conversion Notes topic.
