Perhaps!

There’s a Loft operation in the "2D –> 3D” submenu, which takes in two 2D shapes
and generates a 3D loft between them; you could repeat this a few times to stack up
something like that screenshot.

You can use the Loft command multiple times:
It takes a lower and upper shape (as well as Z values), and gives a smooth blend that’s the lower shape (A)
at z0 and the upper shape (B) at z1.  If you put two lofts on top of each other, you should see a blend from shape
A to B to C (at z0, z1, z2).

Here’s a circle blending into a rectangle blending into a triangle:

In Openscad i do it in 2 shapes ( the picture ). But i need for 3 shapes to be done in one piece. 

Can be done ? Or with spline command? 

Is a big lack of such a possibility in this programs for such a solution. And my project is basid just on this kind of work.

If have any idea,let me know please.

Thank you,Roland.
