Lisp to span multiple drawings?

I may have to create some very large drawings (some 75mb size) that are
quite unwieldy and Autocad 2005 cannot seem to handle them (error: Exception
occurred: 0xE0000001; warning: unwind skipped on exception). I am running
Win2k Pro on a Pentium 4, 3ghz with 1.5 Gbytes of RAM with nVidia car and
256 mbytes of video RAM.

Instead of creating one large drawing, I would like to create them
(automatically) in segments but there are at least two problems that I can't
see my way through.

1. Autolisp can't span different drawings, ref. Help, "...can only work with
one drawing document at a time ...". "... You can access multiple document
namespaces using ActiveX automation ... will be in an unstable state and
likely to fail."
2. Can I plot more than one drawing (without using Xref) to a large format
plotter (with paper roll) sheet without unclamping the paper. Let's say
these separate drawings are plot plans of homes and I want to plot the
entire subdivision so each plot plan is precisely relative to the next, etc.

Any tips?

two things to research... VBA seems to be your tool of the hour. It can
handle editing several files at once.

otherwise, a script to:
Open dwg_1
load LISP_of_choice
Save dwg_1
close dwg_1

.... repeat for Dwg_2, _3, etc.

I'd advise copying files to a working directory, process them there, and
return clean files to the location desired.
