When I was in school we used CAD2001i, (I am now using 2004) there was a snowflake icon on the tool bar that you could click on, then click on a line, and everything on that layer would freeze (instead of having to go to "layers properties"). I am not sure if this icon is part of the program or if it was something that one of my classmates created. Either way, does anybody know where to find it?
