Open multiples and write to 1 file using edg?

Good morning group.

I need to open several dgn files and get some elements from each file
then open a final.dgn and write all of these elements to the final
file.

Based on edg commands, only 2 files can be opened at a time. Is this
correct?

Also, is there an alternative to the open command - like open for
append instead of open (which will delete any existing file)?

Thanks.

 

Easy look at the edg and open commands using help

you can enter EDG opening a file, set a search , then use the command OPEN
to
open a new.dgn
write whole

use the command EDG
to open another.dgn
set search

and write whole

don't forget to CLOSE the new.dgn file

used EDDG like this to extract all elements on a certain level and copy them
into a new isogen piping iso drawing
