YES, it works PERFECTLY!!
you saved me hours of meaningless brainwashing wok
THANK YOU

ok, so this is my problem:
imported autoCAD plan into SketchUp, but it has only lines no faces,
do I really have to draw all the faces manually? The file in CAD was perfect
snapping faces goes without a problem and very quickly but it is the plan of the small town!
I will need a lot of time for this no-brain job just making faces from lines, I try drawing a big
rectangle over it and intersect it but no good
Do I really have to do this face by face?
Please help!

ok, I know this is stupid question, and there probably is 100 years old solution, but I can' find it..
thanx in advance
