Re: Hypothetical situation

I used to design hinges, so I needed an assembly with a stationary
design component and a moveable component for use at higher levels.
This allows for a moveable component that references fixed in-context
definitions.

For the stationary "Design position" component, I used an envelope
instead of a regular component.  The envelope could be used for in-
context design, but would not show up in BOM or upper-level
assemblies.

Over the envelope master I placed a regular component of the same
model.  The regular component was mated to the envelope and placed in
different positions as needed.

I have an example at <http://www.esoxrepublic.com/models/>,
