Could someone please give me a bit more detail about how this tool works? I am learning to use autodesk architectural dekstop but I have hit the stage where I use this during the tutorial and it is a bit vague. I have "some" autocad knowledge but not a huge amount. If someone could run through how to do this in regard to the tutorial (although through some miracle I have managed it by clicking on enough things) and what each of the options mean it would be most appreciated. Thanks Cunning
