Solidworks vs. Pro E File Size

Hi all,
If two parts with identical geometry are modeled on ProE and
SolidWorks, what are the differences in file size?

I have received a large .stp assembly that was originally made in ProE.
When I try to open it in SolidWorks I pretty much run out of memory
trying to converting all of the parts back to .SLDPRT and SLDASM. The
supplier of the model says that my computer is equivalent to what they
have used to produce the model in question and that it should handle
the conversion no problemo.

I'm just looking for a little insight.

Thanks
Steve

 

I personally absolutely hate dealing with .stp files. In my experiece
they always seem to prove the most unreliable unless going from Catia
V5 to SW.

My guess is that this .stp file is a fairly decent size then and SW
tends to be very cumbersome handling large .stp files. I would first
try and get an .iges file or maybe the]
native Pro-e file ( SW can open certain native versions).

Here is some info. from the SW help file.

Importing Pro/ENGINEER Files into SolidWorks
The Pro/ENGINEER translator imports Pro/ENGINEER part or assembly files
as SolidWorks part or assembly documents. The attributes, features,
sketches, and dimensions of the Pro/ENGINEER part are imported. If all
of the features in the file are not supported, you can choose to import
the file as either a solid body or a surface model. The Pro/ENGINEER
translator supports import of free curves, wireframes, and surface
data.

When importing an assembly, you can control how to import individual
components. Sub-assemblies are supported as well.

You can import Pro/ENGINEER surface-trim and surface-extend features
into SolidWorks. These features are read in from the Pro/ENGINEER file
and mapped to SolidWorks.

Version Information - Versions 17 through 2001 of Pro/ENGINEER and
Wildfire versions 1 and 2 are supported.

 

1. How much memory is in your PC?
2. What are your pagefile settings?
3. Are you using the 3Gb switch?

Realize that STEP is not Pro/E, it is a third party neutral format and
as such requires, in general, extra processing steps over the native
format.

You don't say how large the assembly is. 100, 1,000 parts, 10,000
parts, 100,000 parts? Inquiring minds want to know.

 

I have 1 gig on board and a page file setting of 1536mb. I dont know
the exact size of the assembly but their are 950 parts converted so far
and that is when it crashes so there are more to go.
In a past job with the same company, Iges files would run me out of
memory, I had them send stp. files and I was able to get them converted
and finish the project.

I just loaded 2007, I need to service pack it up. Then I will give that
a shot.

Pretty meagre on memory. Just setting the 3GB switch may get you
through even with 1Gb of physical ram.

 

Paul,
Although no one else responded or laughed at your response.
And, although I use SolidWorks and for me, it does everything I need it
to do (almost).
And, I really enjoy working with SolidWorks.

I just have to say that this hit me smack dab in the funny bone or
something, I couldn't stop laughing. I've never heard of any software
package's workings refered to in such a maner.
Just hilarious,
Thanks & Happy New Year,
Eddie
