Find & Replace Text

[drewd1508]

Hi There,
Would like some help on a small problem that i have. I am trying to do a batch 'Find and Replace' exercise on a batch of autocad drgs. ie i need a program of some sort that will open a drawing, find a series of text strings and replace them with another series text strings and then save and close the drg.

old text string could be say 537:00089 and new text string would be 537D:0032. There could be dozens/hundreds of numbers within a drg.

Any ideas?

it would be a relatively simple task for either LISP or VBA.

Are you saying you have a list of numbers to look for and whenever anyone of them is found it is replaced?

Will at least one of the numbers appear in every drawing or will it not occur in othes?

Will the number appear on their own or will they be part of a text string?

ToolPac has a routine to do this. I have used it several times with success.

If you are using vb, then create a selection set of all text and/or mtext and then cycle through each one and then use the Replace method in vb.

Hi

I need to make it clear that it is not the same text change in 100 different drgs. it is up to 100 text changes within a single drg, ie 100 different text strings each text string being a different no. (Autocad 2007)

Cheers

It is possible. The code would just have to be written for your parameters. Still start with a selection of text, then cycle through and apply your test. What is it you want to change and how? (your if/then's)

I have series of schematic diagrams which have equipment shown on them ie valves/pumps etc. Next to each piece of equipment is a unique reference no eg '537:00989' inserted as dtext. This reference no has to be amended for each piece of equipment. I am trying to work out a quick way of identifying every ref no within a drg and then replacing each no with a new one.

are you asking for somebody to do it for you or are you looking for guidance on how to write a routine?

[drewd1508]

Im looking for guidance on how to write a routine as i have no autolisp/vba knowledge!

[dbroada]

.. as i have no autolisp/vba knowledge!

probably leaves me out as I don't have time to do a good job.

Before you start coding write out what you need to do in psudo code. Something like...


create a lookup table of search text/replace text
get all text objects within drawing
step through each piece of text
if serch text is found, go to lookup table and replace
when all text has been searched save drawing

that can be expanded as you realise more steps are required
both VBA and LISP are suitable for this sort of task but they can't (easilly) be mixed.
