Easy way - insert a box object in the wall (disable magnetism) a few mm deeper than the wall. Add your favourite oak texture.
A slightly more challenging would be to design your own window in Blender, Art of Illusion, Sketchup or whatever, include the lintel, read up on the advanced properties in the Furniture Library Editor... etc.
On a very practical note, please be careful if you are about to add the oak beam as a lintel to an existing wall physically. Messing around with structural elements of a house can be risky - and certainly much harder than adding the lintel in SH3D...
ok
PS - the previous thread (5364) has its origin in a stone house on the FR/DE linguistic border of Europe.
