Element ID's

What's in a name? In Revit, not much really (outside of your office naming conventions that is), but what does hold a lot of value is an Element's ID. Yep, in case you hadn't figured it out yet, your 3D model is really just a massive database of numbers, numbers with parameters, and each object in your 3D model has to have some sort of way to distinguish it from the next 3D object, after all that's sort of what makes Revit "smart", right? Why is this useful? Because when you run into modeling errors (like the one below) Revit tries to tell you where to go to fix your problems, but in a slightly obscure way. 

Revit gives you the error and then it gives you that "Element ID" of the object that is causing the problem. This is important because let's say your moving a wall on level 1 that extends multiple floors and it's causing a ceiling sketch on level 4 to become invalid, how do you know which ceiling is getting messed up and where it's at? You can click the "Show" button to try and find it but if you've tried this you may have noticed it's not always extremely helpful or specific and can take a long time to cycle through unopened views. What you can also do is jot down the element ID number, hit cancel and then track down the offending element on your own; to do this you go to the manage tab and choose the "Select by ID" button, it helps to have a 3D window open for this, if needed you can even choose to "Isolate the element" in your view to narrow it down.

It's not an earth shattering tip, but I find a lot of people don't realize that the obscure warning box and Element ID can actually be pretty helpful if you know what to do with it. How do you use the select by ID button? Have another way to find errors? Let us know in the comments below! Thanks!
