Yep thats the examples I have been testing on.
(I was using section arrows ie: Section A on dwg M1 very much the same)So I'm in the ball park.
What I am doing to over come that is using a find feature that will zoom to the block/attribute in question where you can select replace or go to next, this basically will loop through all the blocks in the selection set. In your case a block called 'detail' which you will have highlighted in a block list on the form or you have an option to select a block from the screen.
So as it loops from one block to the next you click 'replace' and that will update just the one item then go to next.
(the same way you do a search and replace in any text editor) This might be a bit of a pain if you had heaps of blocks with the same value but only wish to replace a couple of them.
I also have a replace all option, which will replace all attribute values as your eg:A3 to A4
(I credit the above ideas to Daron)I still have a little tidy up work on it, I have the forms all done. All I need to do now is just fix up the loop through each block to replace item one at a time.
I like this program if I do say so myself.
I hope to post gatte.dvb version 2 (Global Attribute Edit)
tommorow night.
