reverse explosion

I have an assembly that I animated. I basically animated the parts to show how they would explode. I had to manually add the components at each time interval. Once I got everything to show as exploded, I want to reassemble the models. I basically need to just reverse the steps that I did to create the explosion. Is there an easy way to achieve this?





Thanks.

Go to:
ConfigurationManager and
Open your explode view (double click on view name)
Right click over the view name and choose..
mmm...
"Contract animation" or something. I`m not sure
I have the SW2008 in spanish

sorry for my English
Good luck
