loft multiple closed curves within a containing curve

There is here, two different lofts:

-A Loft between the biggest rectangle with the medium one

-and A loft between the biggest rectangle with the smallest one. 

I've added in white big lines, what could be the loft between the three at the same time. This is actually what im trying to achieve.

Could it be possible to loft the faces outlined in white, using the loft component with 3 curves in input? 

Note this is what happens when lofting the three curves at the same time :

Thank you for your help

Do you already try Boundary surface Component ?!

Hi,

You can try to use loft options and select a "Straight" loft type.

But you can't get the image you posted this way... when you loft 3 curves, it is like lofting 1 with 2 and 2 with 3 and joining these (well, not exactly, but in your case it is). In your sketch you are connecting some corners of the medium rectangle to the big one and some to the small. This can't be achieved with a simple loft between these 3 curves.
