DomainRect
This option allows the user to create a rectangular-shaped modeling domain within the Map Display Work Area (MDWA). Once selected, indicate the position of the first vertex with a single LM click, and indicate the position of the vertex diagonal from the initial vertex with another single LM click. Click 'SaveShape' to finalize/close the domain rectangle.DomainPoly
This option allows the user to trace out a polygon of any shape as the model domain. Once selected, single-click the LM button to define the vertices of the polygon that will define the model domain. Click 'SaveShape' to finalize/close the domain polygon.DM from a .txt file
This option enables uploading a .txt file with the coordinates of polygon to serve as the model domain.The following describes the file format (line-by-line text inputs). Each step represents the expected input (left) and an example of text input.
- Projection System file contents and Feature name(s)
- Units:
- Number of features contained in the file
- Number of vertices in each feature
- Coordinate for 1st vertex, for 1st feature
- Coordinate for 2nd vertex, 1st feature

Enter 'PCS:', then copy and paste the contents of the prj. file associated with the feature; then enter 'Zones:' followed by the desired zone name. Note that, if more than one zone feature is added, the first zone will be used as the domain polygon.
| Lat-Lon |
Enter 'Lat-Lon' for coordinates entered in latitude-longitude format, or enter 'Meters' or 'Feet' if the coordinates are measured distances relative to the projection system origin.
| 21 |
Typically, this is '1'. Note that, if more than one zone feature is added, the first zone will be used as the domain polygon.

Starting with line 5, all remaining lines represent a single vertex coordinate. The coordinates for a single feature are "grouped together" (one row after another) until the coordinates for all of the vertices have been entered.
