I have got autocad coordination layout with somany blocks and other services. I have arranged the texts and all trenches i have hatched different pattern with different colours to look the drg neat and better Presendation i made the drgs. Now i got the another revision of co-ordination. How to update my old drgs to the newest revision. Can i insert my old drg into my new Revision, i am worried about the blocks. If they changed the blocks in the newest revision, my old drg become invalid. Otherwise again i have to work in the newest revision that is useless one. Can anyone share your inputs
