Autodesk Inventor Assembly Features
These are just like part features, except they can affect multiple parts, are created in the assembly environment, and are saved in the assembly file. Assembly feature definitions are not passed down to the component level. (Not saved in part level)
What are assembly features ?
These are features that are developed in assembly mode, that define a single logical feature that spans multiple parts, such as an extrusion cut through multiple connecting plates etc . . .
Further, these help in defining a specific manufacturing process, such as match drilling or post-machining.
Where can Assembly features be used ?
These can be used when match drilling and pinning is carried out, the holes can only be drilled after everything is positioned and sized as required.
Note: Assembly features include chamfers, fillets, sweeps, revolves, extrudes, and holes. They also include the work features and sketches used to create them. You can edit, add to, suppress, or delete assembly features. You can also rollback the state of the assembly features and add and remove components that participate in the feature.
