I would like to create something analogous to a 3D pathway, with walls and a floor. Something like this:
This was made using a hack. I first extruded the walls (50 pt depth), then the "floor" (0 pt) which had to be translated down to meet the bottom of the walls, because the walls were extruded up and down simultaneously, putting the floor in the middle.
Ideally, I would be able to rotate everything together, and specify the offset (in the direction of the extrusion), depth, and direction of extrusion (extruding up, down, or both) of different sets of objects independently.
But I would settle for just being able to set the direction of the extrusion. Is that possible? Does someone have another suggestion for how to accomplish this?
Ideally, I'm looking for a solution which could be applied to an arbitrary pathway shape (i.e. a curved hallway).
