Deleting rooms

How to get rid of that long list of "Not Placed" rooms resulting from placing rooms then deleting as the model changes.
Deleting from Views removes them from that view but they still exist in the project database.

To remove from this db fire up a schedule (if necessary create one in Proj Browser>Schedules>New

Select "Show" (ribbon tab to right) - make sure fields are set to show "name". Simply delete table lines. Make sure to check each phase (Props>Phase) to locate all the unplaced rooms.
Thats it - gone.

Hack view title

The outofthebox system family anno_view_title  has 4 types for title / without line / without detail ref / det ref with line etc but no option to zap the scale other than no title.

What if you want the title and no scale ( say for an inserted image dragged in from a drafting view )?

In Project Browser > Families > Anno_View_Title I edited (RC>Edit) and saved this as Anno_View_Title_custom. To show changes I changed the scale tag to a "phase" tag just to track the changes on project sheets. Load this into the project.
