How To Enhance Performance in Creo Parametric?

[eneskilinc]

Hi,

We are working on chassis design for off-road vehicles and we have very large assembly files. (Approx 10.000 parts) I am working on projects by excluding or including components but sometimes it takes time to process easy tasks.

 Our computers are workstations and they are very good but in very large assemblies it does not help. 

I know some ways to do but it didn't help much.

Is there possible ways to increase performance? 

Thanks in advance

Hi,

in Task Manager:

• check how much RAM is allocated for xtop.exe process
  • add RAM if Creo has exhausted it
• check processor load
  • many operations are single threaded ... so use Set affinity command to assign single core to xtop.exe process
  • if the core runs at 100% then the only possibility to accelerate Creo is processor overclocking

Hi

I checked the performance monitor. Seems like Creo is using 1/4 RAM of computer. I have 32 GB RAM and Creo Uses 8GB. So I think its normal.

Also i set priority for Creo. Maybe it will help.

And is it possible to change settings in Creo for performance ?

Hi,

Look at xtop.exe process.

Also check processor load in CPU column.

Hi

Yes, I checked that. 

You can see image below.

Hi,

now start time consuming operation and watch CPU value related to xtop.exe process.

Large assembly management is a never ending process. In this post https://community.ptc.com/t5/3D-Part-Assembly-Design/Large-Assembly-Training/m-p/728764 there is a PDF that will help explain some of the aspects of it.

Simplified reps are your main tool. You will have to meticulously maintain your working reps. Make sure you aren't opening your master rep ever (unless absolutely needed).

There is no one configuration option that makes large assemblies perform better, there are some settings that may help tho. This is my list, but it is in addition to our standard config.pro setting so there may be more settings that are helpful and not included in my list. I tried to include "reasons" for my setting choice, which may help you decide if you want to use that setting or not.

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
