Isolate a layer to work on?
It has been a while since I have been here, and a bit longer since I've needed to dig deep in ACAD.I certainly hope this question isn't a little TOO newb-ish, so I apologize in advance! ;o
I have managed to never really use freezing or thawing when making my own drawings, so maybe I just don't understand it very well ... but here's what I want to do:
I am updating a set of plans that has a HORRIBLE lack of layer organization, enough so that I cannot spend the time to re-do to the whole thing and stay in budget.
The floor height is incorrect, and the easiest way I can think of to correct it would be if I could isolate the one layer I want to change so that nothing else around it will get affected.
Is that possible?
Can I select a layer and temporarily say "I'm only editing this one" without having to comb through all the other layers and turn them on/off by hand?
I certainly hope so ... it's literally the difference between a day long fix and a couple weeks. >
I am using ACAD 2004 for this one ...
Any ideas?
Thanks to you all, I'm very glad to see this community still the strongest around! Try the command LAYISO,
oops just noticed the 2004 part, Express tools loaded ? Express Tools > Layers > Layer Isolate command as mentioned above is the best way to go.You do know that it is possible to wholesale select layers with the use of the SHIFT key, right? this is a nice alternative i use more than layiso. it will isolate the selected layers in addition to the current layer, or if you just enter it will isolate just the current layer. the next time you run the routine, it will turn back on all the layers you had turned off when isolating.

Couldn't find that anywhere ... feel like a complete newb again, instead just a partial newb! LOL
Mark: No, I had no clue about that ... do you mean you can select more layers than one to perform an operation, or that it will isolate more than one?
That LISP routine is great BTW!
Thanks again guys!
