Copy&change/count object text

Hello there:)

I have this thing Im very often asked to do.

I have to mark various positions in drawings with text like A1, A2, A3, A4...

The way Im doing it is to copy A1 over and over and then edit text, wich is usualy frustrating and time consuming:x

Is there any way that you can create an block that will automaticly count and write how many instances are in the drawing.

So egsample when i copy A1 it will automaticly turn to A2, then A3, then A4...like a counter

Any way of doing this?

Thanx a bunch!

refer to these threads for info

o.k. thanx for the links, but I thought of something like creating a block, then inserting a filed in it, that will maybe count block instances in the drawing and label them like 1 2 3 4...

Search here I am sure I have seen this recently done by Lee Mac its not hard to do at all

Step 1 search drawing find last number in block

Step 2 insert new block with +1

I have a lisp something like this redoing step 1 each time makes sure you have correct number a problem in mine is if you erase a block number continues from last. I may rewrite.

I have another idea, could this command be used like an counter that could be turned on/off?

When you turn the counter on, it will insert blocks B1, B2, B3, B4, counter off, remains at B4 you are now just inserting B4, then counter on, B5, B6, B7....

Possible or already done by someone?
