How to configure Creo Parametric to increase performance when working with large assemblies?

  • ​​How to configure Creo Parametric to increase performance when working with large assemblies?

  • ​​Default loading times for large assemblies takes to long time.

  • Default spinning, zooming and panning assemblies lags.

  • When working with large assemblies Creo Parametric sometimes freezes up.

  • Overall performance for large assemblies are slow. 

​​For large assemblies some config.pro settings is to prefer:

  • tangent_edge_display solid

  • edge_display_quality

  • display shade

  • shade_quality 3

  • prehighlight no

Tested versions: 

  • Creo Parametric 3.0 M190

  • Creo Parametric 4.0 M090

  • Creo parametric 5.0.4.0

Tests shown by opening large assemblies with different settings:

High resolution configurations for Creo Parametric

  • tangent_edge_display dimmed

  • edge_display_quality very_high

  • display shadewithedges

  • shade_quality 5

  • prehighlight yes

  • enable_fsaa 16

Low resolution configurations for Creo Parametric

  • tangent_edge_display solid

  • edge_display_quality normal

  • display shade

  • shade_quality 3

  • prehighlight no

  • enable_fsaa off

Loading assembly (File --> Open from Workspace)
Avarage loading time approx: 3 min and 30 sec
Comment: Work with large assemblies is very slow

Comment: Work  with large assemblies goes very smooth 
Different tests shows speed increase between 100-150%
  • In addition to this from  Creo Parametric 4.0 and later "automatic rep" is introduced to replace earlier versions of representations.

  • This should be used by users that are working with large assemblies at all times. 

  • Tests shows speed increase of 400% of the same assembly when opening the assembly using "Automatic rep" instead of "Master rep" with the following configurations:

    • tangent_edge_display solid

    • edge_display_quality normal

    • display shade

    • shade_quality 3

    • prehighlight no

    • enable_fsaa off


Recommended setting to use is to set config.pro: open_simplified_rep_by_default yes
​​This will prompt the user to choice which representation that should be opened:
