Arrays - Part II

I can't believe I forgot to mention one of the most overlooked "problems" with arrays in Revit; the question or annoyance that most people run into is how arrays lose their "intelligence" after copying or mirroring them in Revit.



In the image above I've mirrored the arrayed group of chairs on the left over the line in the middle and the array on the right when selected is now not an array at all, it's just 4 groups that are no longer associated.



The secret lies in the original array line itself, that line, the one that shows up next to the array and lets you change the number of objects inside of the array, is actually an element in and of itself, and you need to select it too before you perform the mirror or copy function.

 Now you can see that after I've mirrored the array the new array has an array object associated with it and will let me change the array after the fact.

Arraying Arrays

Every once in a while I hear a newer user to Revit talk about how limited the array tool is in Revit compared with Autocad. In autocad when you use the array tool you are asked to define columns and rows, creating an array that extends in the x and y direction, but in Revit it only asks you to define your array in one direction, which at first seems limiting. So how do you create a multiple array in both directions?? Well quite simply you array your array:




And the best part is, you can modify the array after the fact by modifying the arrayed groups.



And you can continue to array arrays and put arrays inside of other arrays, and always come back and modify any portion of that "super array" It can actually get a little mind boggling, and makes Autocad's array tool look pretty simple in comparison:
