Need CST macro that changes the parameters and updates structure

Hello,
I need a macro which changes the parameters and updates the structure.
To change the parameters I use "storeparameter" command
But the structure does not get updated.
Does anybody know what is the VBA command for f7?
Thanks
Katto
PS tried command UPDATE and is did not work.

I am currently working on CST macro.
If you need, plz contact me at haidang83@hotmail.com

I use Rebuild instead of UPDATE in VBA script

thanks, that works
