Select a modelspace drawing and assign it to a layout viewport

Helloo, 

I have three drawings in modelspace and three viewports in one layout (paperspace), I would like to select each modelspace drawing and assign it to each layout viewport. Could it be?

I'm using Visual Studio 2012, .NET Framework 3.5 and Csharp.

I'd appreciate any ideas.

Greetings from Venezuela,

Nena.
