When
you select items in the graphics area or FeatureManager design tree, context toolbars appear
and provide access to frequently performed actions for that
context.
The tools in the context toolbar are a subset of items previously found on
the shortcut menus.

Context toolbars are available for parts, assemblies, and sketches. In
drawings, you can access context toolbars and menus for centerlines, sketches, drawing
views, and markups.
