Converting 3D Measurements to Comments
Unlike with the other forms of commenting, you convert measurements to comments in the Model Tree pane. Right-click the plus sign (+) for the measurement view you want; its list of measurements opens. Right-click the measurement to display the shortcut menu, and choose Convert to Comment.
If you decide to convert the measurement to a comment as you're measuring your drawing, select the Hand tool, right-click the measurement, and choose Convert to Comment from the shortcut menu.
