Projected geometry remains associated with the part from which it was
projected and automatically updates to match changes in the original part's
geometry.
When you project geometry from an existing component onto a new sketch
it becomes reference geometry. You can use reference geometry to create an
adaptive matching part that automatically updates to reflect any modifications
to the outer boundary of the component from which the geometry was
projected.
Use the Project Geometry tool on the Sketch toolbar to project faces, edges,
and features onto the current sketch.
Projected geometry is positioned normal to the current sketch plane. If the
selected edge lies in a plane that is not parallel to the sketch plane, the
projected geometry is different from the original sketch. Reorient the view to
the sketch to see a true view of the projected geometry.
Subassemblies In Place
When you create a subassembly in place, you define an empty group of
components. The new subassembly automatically becomes the active assembly,
and you can start to populate it with placed and in-place components. When
you reactivate the parent assembly, the subassembly is treated as a single unit
in the parent assembly.
Optionally, you can select components at the same assembly level in the
browser, right-click, and then select Component ➤ Demote to place them
into a new subassembly. You are asked to specify a new file name, template,
location, and default bill of materials structure. You can then move
components between assembly levels by dragging components in the browser.
