Topic: How do you pick 0,0?

[Bob Wahr]

yes, but we must assume that the person updating that floor plan wouldn't just move it in relation to 0,0

Spoken like a man who doesn't work with Architects much.

You could conceivably go into the floor plan and change the BASE to where you need it. The word "Datum" comes to mind.

Interesting.  I will have to try that. 
This last job I had to move the floor plan ( It took me two days to come to that it was the lesser of two evils) and I paid for it every step since then.

I've seen archies move floor plans anywhere from a couple of inches (which is really annoying) to thousands of feet from the original position. Now, I check each an every one or use craig's suggestion from above and use a reference point like a column line intersection as a base point for copy and paste.

I've done this countless times with plant layouts, substation layouts, etc. The command "BASE" in AutoCad can be very useful, as well as "SCALE-->REFERENCE" for "aligning" floor plans/civil data and what-not, I don't see what all the fuss is about.

I have used Base for cleaning up of new created blocks, but never thought of using it on xrefs, which are really blocks.

Aaaaahhhhh the reference option.  Half my user did not how to use that option.  Tisk, Tisk.

Can I change my original post on how "we" do it... it seems some people here also use the electronic dart method... I've just come across one where the drawing is 1000's of metres out from where it should be... at least I think they should be... now to try to work out which of the drawings have the correct 0,0. What a royal PITA

[daron]

Well, in the past if I had to update an xref and the new version had a different insbase variable than the first, I'd open the old drawing and draw a line from (getvar 'insbase), then snap the end point to a point on the house that is the same as on the new version. Then I'd copy the line using copybase and select the endpoint of the line (the part connected to the house. Then I'd paste the line into the new drawing using on the same point I copied it from. Finally, I could either set the insbase variable to the startpoint of the pasted line. This will set your xref in correctly.

As deegeecees said, the command BASE can be very useful to solve the problem too.

We have (10) cad operators who base everything off 0,0 and (1) real drafter that uses 0,0 for the center of everything.
That way the world revolves around him.

Sorry couldn't resist
