Hi, The closest analogy I can think of is like when you take a screenshot, you drag a square over the screen (I'm taliking Mac OSX), what you get then is a nice neat clip of everything that is within the marqueee- see the attached image. That's great but it's a rasterised .PNG and can't be edited, not to scale etc. imagine now that that screenshot was Vectorworks lines (vectors), then you could edit it in VW. I think it may be possible in a 3D view but it would be so useful in 2D as you could then scale it up, add colour or other detail. to show variations of one particular detail
