Which feature is commonly used to simplify large assemblies?

Using the suppress components feature is an effective method to simplify large assemblies in Autodesk Inventor. By suppressing components, you temporarily remove them from the assembly environment, reducing the computational load and enhancing performance during modeling tasks. This allows users to focus on specific parts of the assembly without being overwhelmed by all components, which is particularly beneficial when dealing with intricate designs that contain numerous parts.

This approach is not only essential for improving navigability and reducing lag, but it also helps in streamlining the assembly processes, such as applying constraints or performing modifications on selected components. In contrast, other options like grounding are primarily used to fix components in place, assembly visualization focuses on analyzing the assembly attributes rather than simplifying it, and part modeling pertains to creating individual parts, which does not directly aid in simplifying large multiple-component assemblies.
