Monolithic slabs patio/porch/garage drop

This probably wouldn't be an issue when a brick ledge isn't required
but does anyone have tips on how to model a patio drop?

For example, i have a covered rear patio, i need the footings to continue 

for the patio floor slab at the brick ledge depth. I'm able to model a 2" drop for the patio

but when it reached the outer edge it auto places a curb to reach back to the floor level.

 

I guess its kind of like a garage drop, how there's a curb around for the stud wall,

but at the garage door it doesn't curb due to the garage door threshold

Drop the Patio Floor the Depth of the Brick Ledge? 

 

Or as Eric mentioned post the plan and/or pics otherwise it is a guessing game , and not many want to play "20 Questions"

Images of patio w/ & w/o walls
& lowered the absolute elv. of the patio floor.

Now granted, i can manually edit this one footing on the patio end to remove
this curb, and model it to match the other footing depths but on any of my projects this seems to throw a ton of other things way off and it

turns into a big mess elsewhere. I was just hoping there was something I'm missing in the auto/defaults
because this is a pretty basic detail on mono slabs.

Lots of variables without seeing the plan file.  If this doesn’t answer your problem your best bet is to provide the .plan file.

 

My Guess:

You already played with it before dropping the floor and manually adjusted that wall already.  Open the wall dbx and select default wall top and bottoms and see if that fixes it.

 

Otherwise too many variables to keep guessing.

Default wall top & bottoms are "greyed out"

That tells you you have not "played" with the wall in 3D/elevation which isn't recommended as standard operating procedure....(SOP)  in chief.

Right, i dont think the other guy read what i wrote

i CAN manually edit this into what i need but that defeats the purpose of what im trying to accomplish 

which is like you said SOP.

*I keep my Autocad subscription because of stuff like this, if theres no way around manually editing

a slab patio like this, i feel like its way faster to just do it on cad.

 

I do like how CA implements a garage drop into the foundation build dialogue, if there was
something similar for poch/patios that'd be great

This Option works fine IF , you don't use the Auto Monoslab foundation.   *Chief likes Monos all at the same floor Height

 

Chief Cheats and does not actually build a monoslab it is really a stemwall foundation made with a 16" thick stemwall and a 4" height to match the slab thickness so I use the same method , only manually, then add a few CAD lines as needed eg if you need a chamfer where you are?

    it may still show issues in 3D though

No I did read it, however 95% of the time when something similar to this is posted here that is what it is caused by.  Many will try to fix it and at one point actually fix it but the second that you manually adjust a wall in elevation the dynamic auto build heights are removed so even if the item gets fixed it won’t adjust the walls after that unless you have the default top and bottom heights selected.  In your case since in the view you showed the other heights were correct that was a starting point to rule out the issue since we didn’t have a plan file.  But what Glenn is showing above should get you to what you want.
