2001PLUS VS 2004

I'm solidworks 2001 plus user and I would some information about 2004 release speed, becouse I tried the 2003 but was very slowly than 2001 plus.
Can you tell me if 2004 improved in draft mode respect my version that in not very good? Thanks a lot -- Gianluca

In my opinion, stick with 2001 Plus, the last good working version. We have had a painfull upgrade to 2004, it also cost about 1000 dollars per workstation to upgrade video and ram to cope with the 2004 version, in the meantime we hit penalty clauses in the contract we were just starting due to the consistent crashing and inability to cope with large assemblies. Just one persons view, others have had no problems, depends on whether you just work in simple details/weldments or need large assy capability. We are still not satisfied with its performance. We discovered that resolving large models in a large assy caused it to crash, and then found that the model we had tried to resolve was now three times the size. Keep backups handy.

Gianluca,
I haven't used 2001 Plus in a long time and can't answer your comparison test. However I can tell you that contrary to some users experience my large assembly mode experience with 2004 sp0 was good.
My machine was a Dell 360 w/ 2.4 GHz P4, 3.00 GB RAM, XP PRO SP1, and (QUADRO NVS W/AGP8X W/64 MEG RAM) game card.
My large assembly is:
TOTAL COMPONENTS: 15285
PARTS 12439
ASSEMBLIES 2846
It loaded in the following times:
Lightweight 56 SEC
Resolving from the LW load 88 SEC
To load fully resolved 3:13 MINUTES
I hope this helps.

Approximately: 250 original parts & 90 original assemblies

Does this assembly have any errors, in-context parts, flexible sub-assemblies, sub-assemblies with multiple configurations, mates with invalid faces or over defined mates? Also are there many undermated parts?

Paul,
I no longer have convenient access to that assembly, but have the following:
Assembly: Total components 13801 total parts 11382 unique parts 120 sub-assy 2419 unique subs 86 resolved 0 suppressed comp 172 Lightweight comp 13629 top level mates 24 top level comp 8 max depth 6
AMD 1.8 Ghz processor w/ 512 meg ram, Quadro4 750 xgl
To load lightweight = 58 seconds to fully resolve after lightweight load 92 seconds
The assembly has NO errors. The assembly has many in context parts, features, and component arrays. Most parts are fully mated. Nothing is fixed. There are no mirrored parts in the assembly anywhere. There are still a few mates with invalid faces in the assembly. These occur when I've changed something and not caught up the mates. I delete them whenever I find them and remate to component in the lowest assembly possible. There are no over defined mates in the assembly. (However, there are ten mates that I feel should show as over defined and they do not. they are intentional. I added a point-line coincident mate to assist SW in being able to solve an already fully defined mate. SW needed the assistance.)
There are still some underdefined mates. I'm fixing most of them as I get to it. This is a different assembly from the previously mentioned assembly and I'm running it on a different computer. The assembly size is 6.4 meg after ecosqueeze (I do not remove the display list or the preview image). The assembly includes structural steel, fasteners, motors, gearboxes, cotterpins, chain, etc., etc.

Any toolbox stuff?
Any flexible sub-assemblies?
The unique parts count seems quite low for an assembly that size.

I had 2000+ fasteners this includes bolts, washers , nuts, and cap screws. All fasteners were copies of the toolbox part and all unnecessary configurations were deleted. Nuts are drilled out to prevent interference with the bolts. I have sheetmetal self drilling self tapping (SDST screws), they were down loaded from McMaster-Carr. I also have square beveled washers. One of the down loaded parts came in as a 2 meg file. I remade the part and it shrank by 6+ times.
There are no flexible sub-assemblies
When you say the parts count seems quite low for assembly that size, I take it that you are complimenting my design skills!

Paul,
My assembly now is:
Total components: 14547 total parts: 11964 unique parts: 120 Sub-Assy: 2583 Unique Subs: 86 Resolved 0 Suppressed 172 Lt Wt Comp 14375 Top level mates 24 Top level comp 8 Max Depth 6 \ Time to load Lt Wt 37 sec Time to resolve 100 sec Time to load resolved 174 sec
I changed a couple of features and added some more assemblies
Tom
It appears that changing a couple of features (it affected 282 parts) has reduced the Load LW time.
I really don't understand all of the variables. But, I can change the assembly width by 1 foot and its height by 6 inches and the width change will add over 550 parts to the assembly (required by new width) and the height change will adjust the dimension and change length on over 50 parts.
The assembly still handles (O.K.)
I have sheet metal parts with six flanges and numerous slots and cutouts.
There must be something that I'm doing or not doing that greatly affects the assembly resolve times. If we can figure out some of these variables, maybe SW can fix the ones that are really slowing down the process.

Tom,
Getting apples to apples comparisions isn't necessarily easy; however, how many users do you think have your system's resources or better?
I think if a survey were conducted, your hardware would leave a large percentage of computers running SolidWorks in the dust...
Unfortunately, programmers may assume that most users have the latest & fastest, but the reality is far different.

Per,
That's why I'm trying to send as much info as possible. Some people are finding that SW 2004 is a real DOG on large assemblies. I've found that it outperforms any other version I've used. Maybe I'm just getting better at it?? I pay a lot more attention to how I set them up than I did before.
I wouldn't say that I'm as good or better at large assemblies than anyone else, so there must be some differences in how we set them up, parts design, or something. I would like to find out what it is, because I don't see assembly sizes decreasing in the near future.

It's been along time since I too have ran 2001+ but I know that when I switched form 01+ to 03 I did't notice any slow downs. I wasn't doing large assemblies then, just advanced injection molded parts, but was often working w/ 15+Mb parts. Now I am working in 04 and have noticed a slight drop in speed, but it is more than made up for w/ the stability it has brought alone. I have two other guys here working on 04 one of which is happy w/ it other than some minor bugs (and it cut his crashes from about 10/day down to 1-2/day) and one guy who hates it w/ a passion. I believe most of his problems are w/ currupt parts though, but I ain't about to argue that point w/ him cause it's a waste of my time. Just my $.02 but I know that if I were trying to accomplish the things I am now w/ '01+ that I would be having a much more difficult time doing it. It's all a judgement call though.
