Copying 4 iviews into 1 iview

Hi All,

I created one model with 4 seperate Iviews.

Now I want to add the 4 seperate Iviews into 1 Iview and create 4 layers which represent the 4 Iviews that I have now. and make tab pages of the layers. The layers and tab pages are no problem but the copying is the problem!

How can I do this, is there a function for this or do I have to create a new model and recreate the iviews again, (they are pretty complex....)

Kind Regards

Marcel
