I found a pretty good lisp to combine drawing files called IMF. However, Lisp has a disadvantage: the drawings will be connected to each other, the name frames will stick together. Now, I'd like to ask the experts to help me correct the distance for each drawing to be 1000, but it's a bit long to combine 30 drawings.
Or if anyone has a good lisp for merging drawings, please let me know, thank you everyone!
