Update title block of all drawing in background using Autolisp

[22352065NTPYQ]

I am using AutoCAD Electrical 2025 and need to update the title block of all drawings based on the Project Description while running the process in the background. When performing this task through the GUI, there is an option called "Activate each drawing to process." If this option is unchecked, the title block updates occur without bringing each drawing to the foreground.

I want to achieve the same background title block update programmatically using AutoLISP. How can this be implemented to ensure the updates occur without activating each drawing?

Thanks in Advance!!

Hi, 

There are 3 steps do this IF the drawing contains 1 layout:

1 creating a batch file

2 a script file

3 a lisp program

OR if its an attribute and multi-layout DWG ,  just use GATTE command.

 hope this info will help you.

I am using the wd_tb_process_one function in AutoLISP along with ace_projectwide_script to update the title block across all drawings. However, this approach opens each drawing during the process. I want to perform the title block update in the background without opening the drawings. How can this be achieved?

then  you must use / search  how to do this in Autocad COM interface  +  batch , here is link:

its like create VBA program that access the autocad database (you must write the link were the program will find the . dwg), then apply the VBA tru  a batch file

Do a deep search for Accoreconsole see if it is supported in Electrical, it allows you to run lisp programs on a closed dwg. You can write a script that opens a dwg for editing, it does not open graphically rather ready to edit, then run a lisp. Very Very fast.

@paullimapa has some nice examples about how to use.

I don't know much about AutoCAD Electrical but perhaps@22352065NTPYQ can share a dwg with the Title Block and then exactly where to locate the Project Descriptions if that's available in vanilla AutoCAD, then that would be a good start to see if Accoreconsole is the way to go or not.
