Face Hosted vs. Element Hosted

Trying to decide which is right for your project? This is an important decision that should be made as early in the process as possible. Here are some key factors to consider:

Face hosted components
* will remain in the model when their host is deleted
* can be used to attach to faces in the model or to faces in a linked model
* components hosted by a ceiling face do not move with ceiling grid lines (they will stay attached to ceiling face when elevation changes)

Element hosted components
* are deleted when their host is deleted
* must have a host, therefore requiring Copy/Monitor of linked elements
* components hosted by a ceiling will move both horizontally and vertically with the ceiling, maintaining alignment with grid lines

Your best bet is to use Face hosted when dealing with linked models. In any other case a good rule of thumb is: when in doubt, use Face hosted.
