Do you draw on the 0 'zero' layer?
Do you draw on the 0 'zero' layer?
(OP)
i dont. my co-workers do.
from the begginning when i learned CAD i was taught to never draw on the zero layer. i dont remember anymore why they told me not to. but i just dont.
is there a valid reason why u shouldnt draw on 0?
ps. damn i cant make a poll, owell.

RE: Do you draw on the 0 'zero' layer?
When inserting blocks onto the 0 layer, when the blocks are exploded, the objects within the block migrate out of the 0 layer onto the layer they were drawn onto. Layer 0 probably has other special attributs also, jut can't think of them right now. Nothing to make drawing on it "bad", though...
I draw on layer 0 all the time.

If the Express tools BURST Explode Attribute to Text is used to explode the items will retain the layer and color they are placed on.

At first, I thought they were primitive, but there's a certain logic to it. You put the geometry that's important to the CAM system on layer 0, and stuff that's important to people, like filenames, revision dates and such, on other layers, and you don't have to do any special filtering when sending the file to the CAM system.

well, some useful info from everyone, but i guess what the instructors really wanted was for me to put every object i drew on the correct layer.
thanks all.
RE: Do you draw on the 0 'zero' layer?
At my first job using CADD in '96, EVERYONE put everything on 0. The reason had nothing to do with technical nuances and strategies the other responders have correctly noticed. The reason? When you start a new file, the only layer is 0, and back then, noone (or at least, I) did not have AutoCAD in college. We had no clue how to utilize the full power of CAD, we were basically using hand-drafting strategies. Although I quickly caught on to Layering, it was years later until I actually figured out the concept of Paper Space, for example.
I think your instructors were trying to get you to create and use layers, so the CAD file would be most useable and re-useable. You are lucky to have had an actual CAD course, I've been using CADD for 9 years now, and I still debate taking a course, because I know there is so much more CAD can do than I am able to allow it to do...hey, this is the start of a new thread...

I do use it to draw blocks, so that the block can be inserted into other layers.

What if you had an empty filing cabinet, and didn't know where the labels were kept? Further, what if someone else had already begun putting everything in one drawer, and you had to add something? And, what if several people were all using the same cabinet, and no one knew where the labels were kept? But wait...what if none of those people used the same alphabet?
...not what SHOULD happen...what would MOST LIKELY happen???
I think this is why you find a lot of stuff on the 0 layer, particularly in old CAD files.

I know some clients will have there own, but does AIA, CSI or ASCE have some basic starting standards?
RE: Do you draw on the 0 'zero' layer?
My company uses it, but we do a lot for the DoD. I wouldn't bet on how "universal" it is.

Thanks for the response. I tried the link, but got an error message. Could you check it?

Or do the folks who use "0" have some kind of object-based management (which I know zero about, by the way).
I don't know, from the very first versions of CAD I was always taught not to use "0" for a drafting layer due to its unique characteristics, which I think are primarily block-based functions. I've always had unique layers for just about everything and yes, it takes some getting used to, but once you get it figured out it's pretty simple and makes managing what my drawings look like pretty easy.
I never learned a different way so I've always just stuck with what I know best, which I guess sounds like the answer for most everyone..
RE: Do you draw on the 0 'zero' layer?
I think if you've used CAD long enough, you tend to try not to use 0 because of it's special properties (a little like the defpoints layer). I tend to use it to draw new objects on, then change their properties to other layers. Then when I've finished, I switch everything off but layer 0 to check if I missed anything.
I think it also depends on the type of drawing you do - mainly new drawings/sketches or working on established drawings/projects, or creating x-refs and blocks for use by colleagues?
RE: Do you draw on the 0 'zero' layer?
so what you guys are saying is:
-lets say a block contains objects from 10 diferent layers.
-make Zero current layer
-make block
?is that correct?
what abuot inserting those blocks. insert them while being current on the Zero layer?
that's what i gather... am i correct?
