Slopes in HeXen?

DooM in HeXen format has 'em, but ZDooM (HeXen) does not! Is there a way I can add slopes in HeXen? It would be REALLY nice....

It's the same line and thing types as for Doom. Apparently the editor config is incomplete.

Looks OK to me. ;)

Make a regular angled wall, and then turn it on its side.

They work like a charm, thanks! It's a WAD I'm making that has the Tome of power, and each weapon has a regular fire and alt-fire so there's 4 modes per weapon, plus there will be 2 new weapons per class altogether and a new class with 6 all-new weapons. But for every decorate addition there's more level, I'll talk more when I have more to show. ;)
