Save As 2000 Disadvantages?

[bgilley]

My office saves drawings back to 2000 to stay compatible with vendors and customers. Are there any disadvantages to doing this? If a feature is lost in the back save, are the features disabled when working in 2006 (with my options set to save as 2000) or do I just mysteriously lose something when I save?

I have seen an approximate 50% reduction in file size on most of my drawings. The smaller ones increased in size and the larger ones decreased. From what I understood about the process, 2004 diagrams compact better. If you use a feature in 2004-06, it will be lost in 2000. So if there is some new feature you want to have available in 2004+, save it as 2004.

For example, I just saved a 2004 diagram that was 146k as a 2000 drawing. it grew in size to 295k! I realize that HDs are bigger but if you are trying to do your backups with an existing 60G tape drive (like I am) and you are trying to do it with only one tape, file size does matter.

The main thing I can think of that you will see is the new Tables feature.
If you use or create tables and save back as 2000, those that open that file
version will have the ability to see the proxy object of the table. There
may be other things that act similar that others can chime in on.

With AutoCAD Electrical, since we use blocks and attribute, other than
placing reports in as an intelligent table, there should not be anything
different with your AutoCAD Electrical drawings between the 2004 and 2000
file formats. As always, it is always best to review to ensure your users
will not be missing any information.

You may try posting this in the general AutoCAD group also to get more
details. I think that with most of the Electrical specific functionality,
you will not see any issues.

I hope this helps and good luck!

My company is implementing ACE 2006 and we have noticed some speed related issues with saving drawings. I have a laptop with 2.15GHz processor and 2GB RAM. It took me approx 60 seconds to save a file using ACE. My default save format was set to 2000 to maintain compatibility with my customers. When I changed the default to 2004, the same file saves in approx 3 seconds! This is a tremendous time savings, especially when performing a title block update on an entire drawing package.

FYI, the original file will save in approx 3 seconds in 2000 format using basic AutoCAD 2006, so this must have something to do with how ACE 2006 handles older ACAD formats.

Write Block and template save seem to save to the "native" format no matter how your file saves work. (e.g. in 2005, if you do a WriteBlock, it saves in 2005 format no matter what)


You can explode the tables before saving -- makes them readable in 2000.

We are saving in 2000 format.
Using both AE2005 and AE2007.

We noticed that 2007 is relatively slow going from sheet to sheet. (slower than 2005).

We did a quick test, with 2007 saving in 2007 format. Seems quicker.

Summary
AE2005 save in 2000 format == okay
AE2007 save in 2000 format == slow
AE2007 save in 2004 format == slow
AE2007 save in 2007 format == okay


We are somewhat unhappy with this, as we were planning to leave some seats at 2005. Not sure why 2007 should digest 2004 format any slower than 2005 does.
