Drawings not on their coordinates?!

[Jr. Piper]

Hi everyone.

I'm new to the board and I have a question for anyone with an answer.

At work, I noticed a lot of drawings that are to scale and have a coordinate sytem on it. i.e. this storage tank is at N.21+03 and another one would be at N.8+87.
OK the problem is... when I do an ID check on the line that has the coordinate on it the darn storage tank that is on the line on the drawing is way off it's coordinate sytem!

So my question is, is there any possible way to restore a drawing back on it's coordinate system or not? If so how do I accomplish this?

Thanks a lot!

What if you select everything and then type in the desired tank cordinate?Will that then move all your other tanks and objects to the correct location?Say the left corner of your tank is at N.23 +03 but it should be at N.21 + 03,select the entire drawing and then use the left corner(N.23 +03 )as your base point then enter your new desired co-ordinate for the corner of the tank,everything will now move in relation to your new correct tank corner.This will only work if your entire drawing has been shifted slightly in one direction
