I'm afraid TT's 'Groups to Components' plugin wont work for this application due to transformations made to the groups - windows rotated to each side of the house. You may have better luck with S4u's s4u_toComponents http://sketchucation.com/forums/viewtopic.php?p=484308#p484308 It is $20, but worth it if you're doing professional work...(if your working with archicad then you're doing professional work). I even use it in place of SU's native create component command...it's much faster, if you don't need the dialog...which you only generally need if you're making a cutting or follow me component. (I work with Archicad exports...so I feel your pain...)
