In a large assembly, you may need some components only for context, or the components you need may be obscured by other components. You can change components to not enabled or turn the visibility of components on and off as needed. Assembly files open and update faster when nonessential components are turned off.
When components (parts or subassemblies) are placed in assemblies, they are automatically visible and enabled. To simplify the design environment, you can remove the enabled status so that their outlines are visible for context but they are not selectable. You can re-enable components as you need them. You can completely turn off the visibility of components and turn visibility back on as necessary. When components are in their non-visible state, you can pause the cursor over the browser node to display the component bounding box in the canvas, graphics display.
Customizing visibility in a large assembly can be time consuming. When you make complex visibility selections, you can save a design view representation . The next time you work in the assembly, you can open the model using the design view representation by name. This avoids loading non-visible components or resetting the display characteristics. You can continue to customize views, name them, and recall them as needed.
When components are placed or created in place in assemblies, they are automatically visible and enabled . You can switch on the enabled and visible status of components independently as your needs change. For example, you can:
