Overview of Revit Warnings

While working on projects, you can view a list of warnings at any time to identify issues that need to be reviewed or resolved. When a warning appears in a dialog box in the lower-right corner of the user interface, the elements responsible for it are highlighted in color. (This color can also be changed on the Graphics tab of the Options dialog box.)

In the case of warning messages, the current operation can still be executed, which is not possible with error messages. Warning messages simply inform you of a situation that may not be what you intended. You can make a correction or simply ignore the warning message.
