■ Describe a specific manufacturing process, such as match drilling or
post-machining.
Components can be constrained to assembly features. You cannot, however,
place a constraint between an assembly feature on one part and the same
assembly feature on another part.
You can roll back the state of assembly features to view the effect of each
assembly feature on the model or to place additional assembly features in the
desired context. When rolled back, newly created assembly features are added
above the End of Features (EOF) symbol in the browser.
Using Work Features in Assemblies
In the assembly environment, work features help you construct and position
components and check for clearance in an assembly. You can also use work
planes to help you generate section views of your assemblies. Create work
planes and axes between parts in an assembly by selecting an edge or point
on each part. These work features are associated with both parts and adjust
accordingly as the assembly is modified.
By default, all work geometry is initially visible. You can turn visibility off
and on for all work features at once. This is important in the assembly
environment, where the display of work features from individual parts can
quickly clutter the graphics window.
Workflow overview: Control visibility of work features in an assembly
1 On the Standard toolbar, click View ➤ Object Visibility.
2 On the menu, turn off or on the work features by type or select All Work
Features.
This overrides the visibility setting for individual work features of that
type in the assembly and in each part in the assembly. Although the work
feature visibility in the assembly is suppressed, individual visibility control
remains turned on.
Replacing Components
You may need to replace a component in an assembly as the design evolves.
