If you are unable to select geometry from other parts in your assembly, where should you look for selection options?

When unable to select geometry from other parts in an assembly, it is essential to look for the selection options available in the Selection Scope in the Top Border bar. The Selection Scope feature manages which components or subassemblies are available for selection during your current operation. This is particularly useful in complex assemblies where you may want to limit the selection to specific components or to include/exclude certain parts based on the task at hand. By adjusting the Selection Scope, you can control whether you are able to select parts from the entire assembly, only active components, or a defined subset of items, thus facilitating precise geometry selection without interference from unrelated components.

While other options may provide varying levels of assistance in the assembly environment, they do not directly address the need to adjust your selection based on the scope of geometry available, making the Selection Scope the most relevant feature for resolving the issue of geometry selection.
