"Well, how did I get here?" One of my favorite verses from an iconic Talking Heads tune. And one that applies to real life more often than I'd like sometimes.
When Autodesk released Revit 2013 they added a new "feature" that took a lot of users by surprise. By simply double-clicking on an instance of a component family, like a door, window, furniture component, etc., you would be placed in the Family Editor in that component family's source file, ready to edit. I'm not sure how this "feature" found it's way into the software, or who the person was that thought it was a good idea (I think they might need a little Revit training), but the user community by and large was up in arms over it. I mean... really... select an instance of a component family and take a gander at the ribbon - what do you see?
What is so hard about simply clicking "Edit Family"? On the other hand, many new users have "double-click-itis" - and when that happens on an instance of a component family, they find themselves in this alien environment that they may never even have seen before. I can't think of anything good that can happen at that point. "Well, how did I get here?" and for the new user more importantly, just where is "here"?
When Autodesk released this "feature" the user community arose in rebellion - the predominant reaction was "What in the heck were you thinking? This is the dumbest thing EVER." Listening to the user community, Autodesk "fixed" the issue with the Revit 2014 release - by making it possible to change the double-click behavior. However it is still the default behavior.
To fix this, and return an inadvertent double-click action to something more benign such as... oh I don't know... maybe "nothing", do the following:
From the Application Menu, click "Options".
Click the "User Interface" option in the left pane of the Options dialog box.
Click "Double Click" Options
Set the Double Click option for Families to something more appropriate (I personally prefer "Do Nothing").
There. All fixed. Until the next release of Revit... and remember that this only affects the current workstation. You'll probably want to make sure this is done on all workstations in your office.
