We have a very old project with lots of information, but lots of rubbish as well. Now we've decided to create a new building, basing on the structure of the old one. To make my work easier I would like to have a kind of trace while drawing each storey.
Another thing is that the previous version was made in ACAD9, and since then we've skipped to ACAD11 and have different attributes, composites and so on. Therefore copy/paste no longer works out.
This project is large enough to be worth trying anyway.
if there's a better way then hotlink, please tell me so
