CATIA v5 How to use Visualization Mode and Design Mode in a large assembly

This video tutorial shows you how to set up the Visualization Mode and Design Mode for components in Product Structure context. The Visualization Mode uses documents in .cgr format. Only the external appearance of the component is visualized. The geometry is not available, which may be useful when you deal with complex assemblies with large amounts of data but only need a few components to work on. The Design Mode command changes the .cgr format of the component into the original editable component document. In other words, geometric data is available. This explains why most of the commands are available if Design Mode is activated. Make sure that the "Work with the cache system" setting is activated in Tools - Options - Infrastructure - Product Structure - Cache Management.
