I am using Creo Parametric Release 9.0 and Datecode9.0.11.0

Bonjour,
j'ai une pièce en tôlerie avec des formes en répétition (nombreuse). Sa mise en plan est très longue à s'afficher et son exportation en STEP par exemple est très longue aussi. Pouvez-vous m'aider à comprendre le problème ?
Peut-être faut-il ajouter une option au config.pro ?

Merci par avance pour votre analyse.

Hello,
I have a sheet metal part with (numerous) repetitive shapes. Its drawing takes a very long time to display and its export to STEP for example is also very long. Can you help me understand the problem?
Maybe we need to add an option to the config.pro?

Thank you in advance for your analysis.

There is not enough information to reply with an answer that is meaningful/relevant. If possible, upload the part or an example of one with this issue along with the drawing. If you are not able to upload the files, then at least show some screenshots of the models/drawings and the model tree with enough detail for a review of the model structure to be made.

 

If you have a pattern in the model with many instances, this can require long regeneration times and also affect the speed of rendering. If you do have patterns, try optimizing them by using geometry patterns or the pattern regeneration options. Use the identical option if available.

Bonjour,

 

Vous trouverez ci-joint les fichiers PRT, DRW, mon "config.pro" et mon "iso.dtl" afin que vous puissiez faire les testqs.

Merci par avance pour votre retour

 

Cordialement,

At a high level these are some items to test

 

Graphics Performance Settings:

  • Set Graphics Mode to OpenGL
  • Enable Hardware Acceleration in Graphics settings
  • Reduce Anti-aliasing to 2x or disable it entirely
  • Disable Ambient Occlusion and Reflections during modeling

Model Display Options:

  • Set Edge Quality to Medium or Low
  • Use Hidden Line or No Hidden display style instead of Shaded
  • Enable Fast HLR (Hidden Line Removal) mode
  • Reduce Edge Display Quality - set edge quality to "low"
  • Enable Simplified Representations to suppress non-critical features
  • Use Level of Detail (LOD) settings to reduce geometry complexity at certain zoom levels
