Sand-bagging my way through learning "Revit Architecture 2008".

The firm I work for does a lot of poured-in-place structural slabs (e.g. Concrete Pan and Joist)

Having some trouble figuring out how to create this variety of floor system.  I have "Revit Building 9 - Student Guide" and a User Tutorial, neither or which seem to describe anything but steel joists or flat slabs.

Any help you can offer would be great.

 Regards,

 Steve

Sometimes you don't need to model everything.  You could do this as a floor that has a 3-4" slap (your minimum thickness) with an area below it that you call concrete joist that is shown as air.  Now your total floor will show correct in depth and in sections parallel with the joist, it will show correctly.  For perpindicular sections, you could use a repeating detail to show the joists.

I did a parking garage where I did model the double tees - very similar to the joist system.  For that, I had a topping slab then the tees were a family with a parametric length that I arrayed across the floor.  This model showed correctly in both directions.  Beams were done in a similar manner.  All is well with this excpt for odd angles or at holes.  Then you need some special families.
