Making unhosted components like unhosted Doors and Windows

Sometimes you may want to use a Door or Window family that is not hosted by a particular wall.  That way, if the host wall is deleted, the unhosted component will still persist.  Here's how:

1. New - Family - Generic Model
2. Draw something
3. Family Category and Parameters - change to Door or Window
4. You may wish to set to Work Plane Based (so you can schedule by Level)
5. Save
6. Load into project
7. 'Door' command - you can choose your unhosted Door family, but it does not need to be placed in a wall.  It can 'live' independently.

These unhosted components can be useful if you want to retain schedule information for a door that has been removed from the project design.  You can make an unhosted door that only has a few invisible symbolic lines in it - nothing that will print, but it will still schedule and can have a Description like "Door deleted from Construction Set".
