Model Size vs. System Specifications

    I am beginning to look at Solidworks for my company. I need to know
    how big of an assembly can Solidworks handle? By handle, I mean to be
    able to open the assembly model and actually work in it.

    Our machines could have as many as 200,000+ parts in the overall
    assembly drawing. This of course would be broken up in smaller
    sub-assemblies. Would this be a problem for Solidworks?

    What kind of processor and memory should I need to handle something of
    this size? What graphics card would be needed also?

    Thanks.

  2. I am running an AMD 64 machine with 2GB of ram and a Nvidia FX3000.
    Pretty much all you can ask for in a CAD workstation. Our largest assy
    is 20,000 parts. Solidworks 2003 manipulated this assy with relative
    ease with hardly no lag in rotating parts and rebuilds and such. We
    upgraded to Solidworks 2004 and the assy is now noticeably slower in
    pretty much all aspects. It is still useable but if the assy was much
    bigger it would start to get frustrating. Multipage drawings of this
    assy are even worse (slower) and would probably have to be divided into
    separate drawing files with a two or threee sheets per file.

    200,000 parts would take a lot of manipulation by suppressing of parts
    and features that are currently needed to be very useable but a lot of
    that would depend on the types of parts have and how they were modeled.
    In my experience, the large assy models and drawings are the final
    things due in a project and the last time you would want to be
    experiencing slowdowns is deadline time.

    I would be very interested to see other opinions on this but i wouldn't
    be to sure that Solidworks is for you. It is a great product but
    200,000 parts are more than I have ever heard of anyone using with SW.

    Has anyone else noticed the slowdown from 2003 to 2004 and has the same
    trend continued when migrating to 2005?

  3. The guys who handle large assemblies don't seem to be inclined to answer
    you, so I guess I'll give it a stab. My first guess would be that you're
    going to have lots of problems with SolidWorks, but it's hard to be sure
    without more to go on. How complex are the parts that make up the
    assemblies? Parts with lofts and sweeps are harder to handle than
    rectangular blocks. How many unique parts do you have? The more unique
    parts, the more memory you'll be using. Still, even if you have assemblies
    of just a few 200,000 rectangular blocks, I think you will probably bring SW
    to its knees when you try to make a drawing, if not just opening the
    assembly.
    You'll want a fast processor, but you may not need the bleeding edge, just a
    bit down from there. More important is getting as much memory as you can
    handle. I would go for 4 GB of the fastest RAM.
    I don't know, but more expensive is probably better. One of the very spendy
    Quadro cards, possibly not the top of the line, as with the processor.

  4. I haven't noticed a slowdown, but we don't do large assemblies or big
    drawings. I have noticed the large increase in file size and the time it
    takes to load and save files when we switched to 2004.

  5. Actually, it looks like David did answer you. It had been so long since I
    read the group that there were more replies available than my news reader
    was set to download at one time.

  6. Hi Kirk,

    I am not familier with the Hardware selections. But I can suggest you
    that, you can handle the bigger assemblies in Soldworks with some
    production techniques. I mean, build the assemblies in planned manner.
    I can imagine that it's not as simple as like the word "plan".
    Presently I am trying to do a equipment with 100,000+ parts. Actually
    my result should be the 2D drawings of the Outline Layout and the
    Various sections of the equipment and later on the 2D detail drawings.
    It would be appreciated if the equipment model is as much as
    parametric!!!
    The plan is,
    - Design a base Layout(skeleton)
    - build the "Sub and Main Outline Layout" model of the equipement
    using "Skeleton" (here I have avoided most of the detailed parts that
    is not really work with Layout models/drawings)
    - I have fixed the eqp. layout design intend in this stage as much as.
    - I beleive I can use the dimensions/requirements for the detailed
    assembly from the sub/main layout models.

    Anyhow I will defenitly have the day which all detailed sub assemblies
    in to one whole assembly model. But atleast SW can work faster in
    remaing days.

    To build the SolidWork assembly models you should have to follow the
    do's-and-don'ts in Solidworks. For examble you should careful with the
    incotext feature. refer the link below
    http://www.frontiernet.net/~mlombard/incontexttips.html

    I assume in near future, high number of Solidworks users will be the
    Large assembly builders. If it is...we need a strong knowledge base
    for the PC hardwares, production techniques, do's-and-don'ts and
    another important one is the "File management system".

    Post your comments.

    Best of efforts.
