I hope someone could help out with the following: I've imported a Revit model wich displays fine in 3D, however in 2D plan the doors show as solid rectangles, windows show as complicated geometries over solid walls, and niches within walls are not even captured (though definitely modelled as were seen in a dwg plan extract from tis Revit file). I''ve changed the relevant symbol options to show 'Top (and bottom) cut' for 'Top/Plan components, wich seems to show correctly the plan of the door
