Can you do a wall footing with no wall on top of it, or do I have to call it a grade beam?
Also - How can I do a cont footing in the interior of a building, down 8" from finish floor, where the slab pours down on top of it and it is centered under a wall above? (I would like to use the wall footing because it would be faster and then I can monitor the walls fron the architect and if the wall location changes then my footing could change.)

You need a wall to host a wall footing
"the slab pours down on top of it and it is centered under a wall above?"
Are you talking about a thickened slab edge?

Well it could be a thickened slab edge coming in from both ways because the slab runs across the footing.
But I would like to link the footing with the wall somehow so that if the wall moves the footing will move with it.

I don't use structural so ....
You might try a slab footing then dimension from that to the wall horizontally - lock it and delete the dimension.

That sounds good - other than do you mean for a slab footing use a concrete beam?
(Is there a "so called command" for a slab footing that I don't know about - I am pretty new to Revit?)

You could use a beam but I would probably use the SLAB tool to create it.

Taefoe5 - are you talking about using the slab tool to create the footing? If so, how?

OK - Not Slab footing - Foundation Slab

Yes, I know about the slab edge, but I really need the slab to keep going and angle (pour) down to the footing from both sides.

Hello.... have you thought about a simple sweep in the floor category to do the drop.? That could have the shape you want and be tied to the wall. And still use the "Foundation slab"<< Not slab edge.
Slab edge could work put you would have to split your floor in two and it would not flex with the wall.

I think the sweep might be the answer. I don't want to put in 10 milliondifferent slabs (UGH)!
(I will try the dimensioning the footing to lock it to the wall and then the sweep.)
Thansk!!!

If you have a gazillion of these, then make a simple extrusion or sweep family. Don't do an in-place.

Yes I will - I have done a few before, now only to check my memory bank on how to do that. :-)
Thanks!

Think you are on the right track, with the sweeps, especially if you are doing infill type structure, which can have multiple steps in the slabs etc. preparing a footing profile system prior to commencing could help so that they will all fit together easily. Good luck.
