Looking to extrude open edges but the extrude nodes: polyextrude, extrudevolume and extrude-old do not work with compile nodes. Looking for an alternative away to extrude and cap open edges. Fine with Vex.

Image: How do I get from A to B.

Transform or peak A, merge with original A, skin, polycap.

Thanks PaQ WaK, worked like a charm.
