Importing and Exporting TIN Ground Models

TIN Ground Models can be imported from several different formats and exported to InfoWorks ICM standard (.IMM) format.

Importing a TIN Ground Model

TIN ground model files can be imported into InfoWorks ICM in several different formats:

When importing the Arc/Info, ESRI Shapefile, 12D, XPTIN or LandXML format files, they are first converted to the InfoWorks ICM native format, and then imported into the master database.

To import a ground model file:

  1. In the Explorer Window, right-click on the Model Group.
  2. From the popup menu, select one of the following options from the Import InfoWorks | Ground model TIN or Import SWMM | Ground model TIN submenu:
    • from InfoWorks ground model file
    • from Arc/Info TIN file
    • from SHP ground model files
    • from 12D files
    • from XPTIN files
    • from LandXML files
  3. A Windows Open dialog is displayed in which you can select the grid file to be imported.
    • If you selected the from Arc/Info TIN file, from SHP ground model files, from 12D files or from XPTIN files option, a Specify units dialog is displayed. In this dialog:
      • Select the type of units, which are used in the file being imported, from the X,Y,Z units used in file dropdown list.
      • Select OK.
    • If you selected the from LandXML files option, a LandXML Surface dialog is displayed. In this dialog:
      • If you want to specify the units to be used by the ground model, click on the Editing units setting button to display the LandXML Units dialog. Specify the units and then select OK.
      • Select which LandXML surfaces you want to include in the ground model from the ones displayed in the tree structure.
      • Select OK.
  4. Click Open (in the Windows Open dialog) to import the file into the group.

Because ground model files can be quite large, the import process may take some time.

 

Exporting a TIN Ground Model

TIN ground models can be exported in the InfoWorks ICM standard (.IIM) format. This file format cannot be edited, but the IIM file can be used for import into a different database or model.

To export a ground model:

  1. In the Explorer Window, right-click on the ground model and choose Export from the popup menu
  2. Choose a location and filename for the exported file and click Save.

InfoWorks ICM saves the ground model into the IIM file. Because ground models can be quite large, this operation may take some time.
