Re: Rib construction

The lower rib in the picture is for the ailerons.
The extra supports are for the spars that make up the hinge area for the ailerons.
The upper rib is the standard rib for the rest of the wing.
The plans show where the two types go.

Re: metal parts

You don’t actually need a CAD program to draw out the metal pieces for the Piet.
Almost any vector graphics program will work.
As will a pencil and paper if you are actually making the parts yourself.

The crossmembers go across the fuselage where the vertical side member junctions are, just like they do on the "short" fuselage.
