Revit Door Families - UK Door Block Library in mm: 14 doors on standard 838 x 1981 and 926 x 2040 leaves, effective clear width marked on every block (DXF - imports into Revit, AutoCAD, SketchUp)

An 838 mm leaf gives 803 mm effective clear width at 90 degrees; the same 838 width in a 44 mm FD30 leaf gives 794 mm, under the 800 mm Approved Document M asks for on a straight-on approach in a new building. Every block here carries that number on the drawing, so door widths get checked before the door schedule is issued, not after it.
