Sill Height Using Subfloor Thickness

Use the Subfloor Thickness field, in the Dimension Marker Panel of Door/Window Settings (or the Info Box), to fine-tune the marker display of your sill height value if your floor level takes into account carpeting or parquet flooring, and if your wall base is not at this floor level.

ARCHICAD measures the height of a door/window sill from the wall base (or a given Story level, as set in the Preview and Positioning Panel.) But if you want the marker display of this value to reflect the real floor level, enter this additional thickness in the Subfloor Thickness field.

ARCHICAD will still measure the sill value from the wall base, but the door/window marker will show a sill height value that subtracts the subfloor thickness from the entered sill value.

For example, say the Wall Base is at -100 mm below the floor level (Subfloor Thickness is 100 mm). The window sill (parapet) height is 1000 mm, but your effective Sill Height, for the purposes of construction documentation, is really 900 mm from the floor. So the window’s sill height, as displayed in the Floor Plan marker, will show 900 mm.

Note: Entering a value into the Subfloor Thickness field does not affect the actual positioning of the door/window within the wall; it is merely an alternate way to display sill/header height in the door/window marker.

Note: Sill height markers use dimension units set specifically for this type of value: go to Options > Project Preferences > Dimensions, and choose Sill Height Dimension.

Some markers have a checkbox to display the Nominal Sill Height (e.g., the displayed Sill value does not take subfloor thickness into account). The illustration below shows the effects of unchecking and checking this box.
