I first heard about this update from the Revit Forum twitter feed:
Munkholm (RevitForum) on Twitter

via AUGIWorld September 2011, page 36:
However, there is a phenomenon in Revit whereas if you
“join” any two solids together, they result in a new entity, the edges
of which are “pickable.”
To illustrate this method, let’s create a sac-
rificial wall at the same location as the wall shown in Figure 9. Join
the wall and the roof surface. Notice that the roof surface now has
new edges where the wall profile line is located.

Thanks for this article Marcello!

You are about to delete a number of model elements, but you are concerned about how many tags and dimensions are going to be affected by this deletion event.

Here is a quick way to check:

  1. Select the elements you intend to delete
  2. Click Group, then 
  3. Click Link
  4. A warning dialog will show up, saying “Elements will be deleted”
  5. Click Expand, then Export and save a list of the affected elements
  6. Click Cancel
  7. Click undo (to undo the Group command)

Now, you can use that list to check check or correct the affected detail items.
