Flags are useful for annotating a design with reminders or suggestions for future changes. A flag is a bitmapped image (raster element) with or without an associated explanatory message. Although the message text is not displayed with the image, you can easily review and edit the text in a separate window.

A set of flag image files is supplied with MicroStation in its image directory, which by default is located in ..\Default\Image\ folder in MicroStation's program directory. .
