8. Window marker

Window markers are used for displaying information, such as type or identification number, about the window on the floor plan. Some markers are prepared for marking the centerline of an opening or showing its dimensions. The Basic Window-Door Marker, the Window-Door Marker -70 and the Window Marker objects can display the unit size of the window on the floor plan

See more about markers at the description of Door Marker NCS, which is very similar to the window markers.
