Double panel on curtain wall

[Szigeti.Eduard]

I created this plasterboard wall as a curtain wall system and I added a layer of plasterboard as panels.

I want to add a second layer of plasterboard on the top of the first one, but I want to start with a piece of 600 mm and the rest of the panels be 1200 mm.

Can anyone help me to do this?

You could place another Curtain Wall. How about that?  

[syman2000]

You can use offset value. So it start 600mm first and then 1200mm for the rest.

Also I would use wall if you want to have double layer Gypsum. See attached

unlock the CW grids to adjust panel.

...how 'bout just scrapping the whole double-whammy curtain wall panel and replacing all the curtain wall panels with a compound-layered basic wall type?  That work?

Unfortunately it won't work as I model for construction, not for rendering and I need every small detail of the wall type so I can accurately animate the whole construction process.

That would solve one problem but will create another.

I need to get rid of grids and lock the both systems together, also I need to put insulation and pattresses and for that I would have to create a different curtain wall for each.

It would work if I could select the second layer separately, but the grids are common for both layers and moving one grid will move both layers and I need staggered panels  

[Szigeti.Eduard]

Yes, they are two layers but they are not staggered. 

It would be great if I could select the panels and replace the first one with a 600 mm panel and continue with 1200 after, but Revit will not let me select the panels.
