I'm sure we have covered this before, but another example of it and its importance has been uncovered. Using a correct family for model elements.
The example today is an elevator door. A generic out of the box sliding door was used to represent a center opening single speed door. Here is how it looked:
If you have ever seen an elevator door in plan, you know that they don't lay within in the wall, but rather on the shaft side of the wall, and unless it is a dual speed single side door, the panels do not overlap. Furthermore, the door is an out of the box sliding closet door. So why is it used for an Elevator door? We may never know.
There are true elevator doors for Revit. I believe the out of the box family library even includes one, but each of the three major elevator manufacturers (Otis, Thyssen Krupp, Schindler) have BIM objects on their website, so a simple visit, a coupe clicks and you can download one. (each of those manufacturers also have full elevator model's that can be downloaded, but we can cover that later.)
Anyway, here is what the same elevator shaft looks like with an actual real elevator door inserted:
