Hiding and Showing Items in the FeatureManager Design Tree
You can hide and show various items in the FeatureManager design tree to help you design models.
When you multiselect bodies, planes, or sketches that have a combination of shown and hidden states in the FeatureManager design tree, the context toolbar shows both the Hide and Show tools. You can click Hide or Show to change the visibility state of all the selected entities.
The Hide and Show tools also appear when you multiselect a combination of hidden and shown planes and sketches.
