How can I slope just a part of my foundation - ie the garage. I have added two split lines for the garage itself, but it won't allow me to add a slope just to the garage area. What am I doing wrong?
Thx,
Marc

Get rid of the slope arrow and close out of sketch mode. Then use Modify Sub Elements to accomplish what you want.

I would use two slabs...instead of adding split lines i would literally split them into two, and have a separate slab for the sloped area with modified sub-elements

Doing it Rob’s way would negate even having to use Modify Sub Elements. Just use the slope arrow when you sketch new boundary – unless, of course, you have more than one slope direction.
Thx guys - I decided to go the separate slab route. I have several other slab drops in this foundation for walk-in showers and some water features so had to do this on other areas too. For an area like the garage on the low-slope side: To build the curb there, is there a difference between using a beam vs a slab for something like this?
For the curb, I would just build a concrete wall a few inches tall and attach its base to the slab.
Our curb walls are walls and our garage slabs are floors. Or do I misunderstand you?
Toan, curb walls are generally the height of the foundation slab (slab on grade construction here in NorCal) and the top of garage slab is 4" below the top of foundation slab at its high point. In the field, the curb walls and foundation slab are done in the same pour, and the garage slab later.
Toan, “garage curb wall” and “garage stem wall” are interchangeably used to describe the concrete wall around the perimeter of the garage area. It is generally 8” wide, and the same ground depth and height of foundation slab immediately adjacent to it (generally 8” above grade here in NorCal). Between those walls and foundation slab sits the garage slab. The top of garage slab is 4” below the top of the walls/foundation at its highest point. That is what I, and I believe Marc, were referring to – not a “curb” in the pedestrian sense.
Dear Barth,
I am having the same problem, and I need to conserve the category of the slab as "Structural Foundation", and when trying to model a foundation slab, there is no option to modify sub-elements.
