Footing Join

[jfjacques]

I've attached the file. 

More often than not the footing is able to join the slab, 

It doesn't seem to want to in this case. Is it because of the the double wall?

You have different materials applied: Concrete, Cast-in-Place gray and CONCRETE, CAST IN PLACE for the wall (&Concrete for the slab)

OR

Switch join order (under join dropdown menu, could be that's what you meant)

The problem with the non-union of materials is that the concrete wall and the floor and structural foundation are  different, so the join leaves a line that represents this difference in materials, the other point is about the structural foundation, just change the order between the structural foundation of the floor.
Another point I saw is that the floor is not touching the structural wall.

I made a video changing the materials, using the Switch Join Order and connecting floor to the wall.

Thanks,

Though these are all valid points, and I realize the wall I sent over in the file was solved by switch join order,: I copied the wrong piece of footing. Unfortunately this was not the issue. 

The issue was my footing direction. If perpendicular to the floor(in plan) the footing, does not join with the slab. Just revit ****ery. 

I therefore had to play with my corner footings so that they were always parallel the side of the wall and therefore the slab.
