Optimizing plot time

I'm plotting some acad2000 drawings but I have a problem. All drawings have
a reference with thousands or maybe millions of little lines (This lines are
not in the same layer) that not appear in paper when I print the draw, and
make the regen previous to the plot too slow (20-30 minutes in a 2'4 Ghz
with 750 Mb RAM ). So I think in two solutions to do print job faster, but I
don´t know how make the routine in my program.


- A routine that let's me delete all little lines in drawing's.

- Work with plt files. The first plot could be slow but the next be faster.
Then I should add a class to preview plt files in my routine without start
ACAD. Where can I found information to make this class, or where can I found
it.



Thanks in advance,


Oscar

 

I had written a VBA routine to find all lines with 0.0 length. Do a filter
Selection for objects which have a Length property, then go through them all
and delete any where Length = 0.0 (or whatever distance suits your needs,
such as Length < 0.0001).

Repost if you need more info on this.

I don't have a link handy, but there is a reasonably priced ActiveX control
somewhere out there (probably more than one). Maybe search for something
like:

"ActiveX control" hpgl plt "plot file"
