2d drawing with architectural desktop 3.3?

In the design content.. there are folders listed with 2d content

No but there is a lispfile that removes all the 3d parts of a drawing - Autozero its called. You run it from the menubar. Otherwise just select everything in the drawing and reduce the Z coordinate to '0'. Either way its a pain. ADT's 3d functions really start to get in the way of normal 2d drawing - if I was you I would switch to AutoCAD full version or AutoCAD LT or go to Microstation which doesnt have any of these problems. AutoCAD are really losing the ball with ADT.

Actually,, if you do this one by one you can reduce it to 2d. Set up one viewport at a time if it hasn't already been setup. Then looking through that viewport.. explode everything. Save As to a different file. Then go into the original again and do the same thing for the next viewport. As long as you are looking through viewports.. you can explode the objects and they will revert to 2d in the plane that the viewport is perpendicular to.
