How to open an older version assembly 3D model from windchill

[Sulibo]

Hello ,

We have a rebuilding project for an older project  that we  delivered years ago,

I have a xml file that they generated after delivery by this function:

Now I want use the old version of 3D assembly model,

Does windchill have some function for this problem, or 

Who have some good experience for  this issue?

You can use the as stored filter by adding the assembly to the workspace. Also to see the "old" structure you can use the filter.

Thank you @BjoernRueegg ，

Now I know we can use "Baseline" solve this kind of problems,

Have a nice day!
