Managing large assemblies in the CATIA V5 system can be very demanding and frustrating to operate. Even with the use of extremely powerful computers, working with large circuits often leads to the destruction of the system with the message "Click OK to terminate". Here are recommendations for optimizing the system in order to minimize the demolition of the program and to make it easy to work with large sets.
A. Cache System
B. CGR Management
You can optimize
C. Display options
By adjusting some of the performance settings, it can be greatly improved. Settings are determined by clicking Tools / Options / General / Display. It is recommended that you turn off Occlusion culling, set 3D Accuracy to 0.1 (increase in value improves performance), increase Level of Detail while Moving (increasing the value improves performance), increase Pixel culling while Moving (increasing the value improves performance).
D. Disable Automatic Saving
By default, CATIA automatically records data every 30 minutes. During the recording, resources are significantly reduced, or the system slows down. You can turn off automatic data recording by clicking Tools / Options / General and turning on No automatic backup in the Data save settings.
E. Stack size
Stack size is the number of "Undo" operations assigned to the CATIA session. Reducing this number increases the memory capacity and thus the performance. To set the value, click on the PCS tab in the General menu.
F. Product Visualization Representation
Opening sets in such a way that all components are deactivated, and subsequently activated as needed, will improve memory utilization. To change this setting, you need to enable the Do not activate default shapes on open option within the Product Visualization (Tools / Options / Infrastructure / Product Structure) menu.
