I've "searched" this topic but it seems most answers are that it's not worth it to model compound slab/roof slopes (sloping more than one direction).  That may be fine for construction documents, but I'm modeling a structure to a high level of detail for use in clash detection in Navisworks, so I need to know exactly where my slabs are. 

 Is there a way to model a "flat" roof of multiple ridges and valleys and varying spot elevations?  I've run into the same problems others have with slope arrows in that I can only slope in one direction.  I would even create separate triangular planes and join them if I could figure out how to slope them in both the x and y directions.

After posting I read "Auditorium Floor with multiple slopes"  Thanks!  I think with the Options Bar / Define Points knowledge I'm well underway.  Finally.

I would use a floor to do this.  You can edit the levels quite finely and in specific places using reference planes. Click on the floor and modify sub-elements.

Tim,

 

I did end up using a floor slab.  It works pretty well, except that the program tends to put some ridges/valleys in places I don't want them.  But I think it will do the trick. Thanks.

"I would use a floor to do this.  You can edit the levels quite finely and in specific places using reference planes. Click on the floor and modify sub-elements."

Why use a floor? when a roof can do the same thing? I think from a technical standpoint the roof and floor are identical, other than the roof is a roof, and the floor is a floor.

As a tip, I found that its easier to use multiple roofs to get the correct ridges and valleys. You can use the join geometry tool to make them act more like 1 object. I make 1 roof that has the main ridges and valleys, then use smaller roofs for crickets.

Look into AutoCAD's site for Revit tutorials.  Which version are you using?  I have found a page for 2010 that has 6 or 7 downloads available that are essentially templates that you use with the tutorial.  One of them has a tutorial on how to do the exact thing you are asking about... for Roofs.  So take a look into that and like others have mentioned; think outside the box and use a roof for your floor slab.  Hope this helps.

The files you are looking for are:

rac_tutorial_datasets_02_i.zip

rac_tutorial_datasets_03_i.zip

Edit: Forget what I said about using a Roof for a Floor slab; while it can be done, this tutorial shows you how to create flat roofs with slopes towards point (drain or what have you).
