drawing scale floorplans in illustrator
i want to draw scale floorplans in AI for interior room layouts, whats the best way to do this as i would like to draw them at 1:1 but for printing they need to be at 1:50 is there a way that i can use "viewports" (the way that vectorworks handles this problem) or is there another way that you could think of, other than selecting the drawing and using object > transfer > scale > 2% ?
Illustrator has no CAD functions. Any scaling will have to be done manually either upon output or while creating.
There are plug ins which may or may not suit your needs for CAD functions. Hot Door's CAD Tools is one major plug-in vendor.
