Echoview allows you to import 2D regions from 2D region definition (.evr) files.
To import 2D regions:
On the File menu, click Import.
In the Files of type box, click Region definition (*.evr).
Locate and select the .evr file(s) you wish to import.
Click Open.
On the Import Region Definitions dialog box, do one of the following:
Click Yes, to delete all existing regions in the EV file before importing regions from the .evr file, or
Click No, to keep existing regions in the EV file before importing regions from the .evr file.
Note: 2D Region definitions are time-based and an import will only be meaningful if the EV file into which you are importing the data covers the same time period as regions.
