Can you "flip" static objects?

Yep pillars and welders like someone stated above is what you should use for walls which are sticking out (pointy outside).

Also you can 'flip' static objects easily, just click on the object and then click on the rotate button at the top right hand side and then rotate.

Level editor is all thats needed, model editor is to edit models map view is to see that things arn't messed up in your map eg. doors open properly etc.

But i recommend that y ou have your game on also especially when scripting so that you can constantly check your map is workign and everythign looks fine, because you will always find that theres something wrogn with your map, epecially with walls within other walls and entitys colliding with other objects.
