Unable to Edit dimension

Hi @YD_4144442 

Thank you for your question! 

I’d like to recommend to bring more details and context to your initial inquiry. For example:

• Does the freeze occur in Sketcher mode or during 3D model editing?
• Is the issue consistent across all parts/assemblies or only specific ones?
• Do you notice any delay before the freeze, or does it happen instantly when you try to edit?

Please add screenshot(s) to better understand what you are trying to do in your process. 

Please refer to this guideline to make your questions more likely to receive a quick and useful answer.

Hi,

Try turning off anti-aliasing, and text anti-aliasing. File, Options, Appearance, Entity Display.

If that works, you need to check your graphics card for compatibility and try updating the drivers if it is supported with Creo. This is common if you don't have a graphics card.
