Config.pro

[mmello]

Good morning members of the Community!

We have a client who wants to see how Creo Parametric performs compared to SoliWorks for large assemblies!!! Would any of you have an ideal config.pro for large assemblies that I could use in a demonstration?

Client wants 30 licenses!

Thank you very much,

This is the stuff I add to my config (but it's in addition to whatever we already have in our standard config, so it's not a complete list.

This is my list of config.pro options that I believe make opening stacks much more reasonable.

Some of this may be out-dated, its something I have kept - added to, over several years.

OPTION	VALUE	REASON
allow_freeze_failed_assy_comp	yes	REQUIRED
atb_auto_check_on_retrieve	off	this should be off, it is on by default
auto_place_max_number	1	this has to do with auto placement of interface components and can slow down assy of hardware with interface enabled
auto_regen_views	no	REQUIRED - you must manually regen sheets/views, otherwise it causes significant delays
autoplace_single_comp	no	Autoplace interface components can significantly slow assy times
check_interference_of_matches	no	it is possible this option can slow assy times when set to yes (default it yes)
comp_assemble_with_interface	none	comp assy is an interface option that may significantly slow assy times
create_temp_interfaces	no	temporary interfaces can significantly impact assy performance
enable_auto_regen	no	enable auto regen Yes (default) has potentially negative large assy effects
fasthlr	no	unknown effects
interface_quality	0	this option when set to anything other than zero can seriously affect print time. It is really for PLOTTING, where a pen would got over and over  the same line.
open_simplified_rep_by_default	yes	recommended so you don't accidentally open the master rep on a large assy
shade_quality	3	shade quality is EXTREMELY DETRIMENTAL TO LARGE ASSY PERFORMANCE
smooth_lines	no	unknown effects

Hello, Stephen.

Thank you very much for sending this valuable information. I'll run the tests and let you know the results. I'm using Creo 10 and I'll see if these options are available there...

Cheers,

You can use simplified reps to speed things up, making some parts/assemblies one of the lighter representations (Graphic, Geometry, etc.).  Also, and this is important, there is at least one setting to simplify geometry while zoomed out and/or spinning.    LOD's (levels of detail) if I remember correctly.  I can't test right now.  What this does it turn geometry into a crude simplified graphic representation.  Look for settings using that term.  I'd give you my config.pro but I have no access to it right now.

Hello..

I thank you very much for your attention and willingness to help me... this client works with 300,000 components and this represents a very large assembly even for Creo Parametric. I'll look for something on this topic. Let's see what I find!
I'll close this call, but working with an assembly at this level will be really difficult...
Cheers,

There is a pdf attachment to the post done by Steven LaPha with NASA. They are the only ones I know that willingly work with assemblies that size.

Hi Stephen, how are you?

What wonderful material you sent me... very good indeed!!! I have to look in detail to understand the whole process, but I can tell you that if there is no answer there, there is no answer anywhere else!!!

Cheers,

I could talk for 20 hrs on the topic of large assembly management between SW and CREO.  The first time SW entered (exposed NX code) large assembly management game was 2014.  Before that laughably a large assembly in SW was 500 parts.   being passive-aggressive, I like to tell people SW has come a long way in 20 years.  I don't have config.pro suggestions, however.    It's always seemed like a political argument making an intelligent discussion comparing the two tools and I've found discussions w/ people who are not knowledgeable on the topic more of a class.

Hello, Bart.

Thank you very much for contacting me. As some colleagues have said, I made some changes to config.pro to get a better result. Of course, the notebook you are working with also interferes... but thank you very much for sending me the information!!! Have a good day at work.
