collapsed wall in 3ds max

I watched a tutorial on how to collapse a wall and though that it was really interesting, so I set out to do the same. The tutorial I watched can be found by clicking on this link: http://www.youtube.com/watch?v=YI9390OxA1U

I wrote down everything needed to do from the tutorial, to create my own collapsed wall.
These are the step by step instructions on how to make this animation work:
 "Create a big plane"
 " Create a small box but just a bit higher than the plane" (This is so when the animation is done the bricks will not fall through the floor)
"Copy the box 6 times along side one another, but not touching"
"build up the box once and set it of like a brick wall"
"use the angle snap toggle and select all blocks and rotate around 90 degrees" do this again with the new boxes selected. Then put them together so they make a square.
"Select all boxes and copy them up 10 times"
This is the end of the first stages now for the technical parts:
Go to "customize" then show UI then show FT
This will open up loads of new tool bars delete all the smaller ones leaving the one big one.
then click "open property editor" once all the boxes are selected
Then put the mass to "20" and click "inactive" and "bounding box"
Then do the same for the plane but put mass to "0"

As there are many other elements needed to further the process of making this aniamtion work, it is very time consuming to write all the instructions down. so if you want to make this from yourself please click on the link, this will show you exactly what to do.

Thank you for reading :)
