Hello, I recently started working with visual script and I ran into a problem, which I can't get my head around why it's happening.

- What I am trying to achieve:
Create a polygon which can be offset by X and Y distance in each direction. Offset the two new polygons by the Z direction and create a 3D solid using the offset lines.

-The problem: No matter which node is used, the polygons don't form a 3D solid and stays as lines.

- Solutions I have tried:
*Build the whole frame of the polygons in 3D lines and connect them via a loft
*Use the two offset polygons (which are on the same plane) to make a surface, which is then extruded. (not visible in the provided images)
*The command sweep

Is this a good structure or is there a better way to create a 3D polygon mass?

Thank you
