Since moving from R14, I have a drawing that takes about 4 minutes to
attach. It has about 100,000 blocks (No attributes). If I save the same
drawing as an R14 dwg, it attaches instantly. The drawing is on my local
hard drive, so it's not a network issue. I have a 1.7Ghz Intel P4 with 1GB
of RAM. Now that I'm working with Map 2004, saving as and R14 dwg is not an
option.
I can attach larger drawings (In R2000+ format) with no problem if the
objects are mainly lines (26 MB with 212,000 objects) or text (15 MB with
189,000 objects). It's when the drawing is mainly blocks that the slowdown
occurs. The blocks are well symbols which are simply a circle with a few
lines - no hatch patterns or anything else.
