Non-Rectangular Wall Foundation

[ronsarlo]

heya...

I was just wondering how you guys are doing your non-rectangular (in section) wall foundations...

When I say non-rectangular (in section), I mean that the top of the strip footing is 600 wide, then 100 deep, then 450 wide at the bottom.

My first instinct was to use a profile, but the "system family: wall foundation" only accounts for 2 possibilities:
a - bearing
b - retaining

both are rectangular (in section).


Have you guys found any work arounds?

thanks!

Hi,
You can modify a concrete beam family. Change the profile in the family to suit.

in place blend or sweep

.... Yeah, I'd rather not do the foundation won't follow my wall?

in place blend or sweep

I was realling hoping you weren't going to say that...
But now that you have.
Can you confirm that you meant Edit Type > Edit Assembly > Sweeps > Choose my desired profile?

thank you!

I would create a new Generic Lined Based Component family. You can set the Category to Structural Foundations.

The idea of using beams makes me cringe...

In-place sweeps is a good alternative. I personally prefer to avoid in-place families.

I agree with Steve's option.
I will advocate that method.

could you do an in place void sweep to cut a rectangular footing into a tapered one? that way your footing would stay connected to your wall and would be recognized as a footing by revit still.

[FOUTJM]

crosseyed's method works really well.

just like everything else in Revit. there is more than one way to accomplish it.

I can't seem to make this in-place family into a wall foundation.
Would I be correct in assuming that since the wall foundation is a system family that I'm out of luck in that respect?


As for the void form, I gave it a try, but it wasn't turning out quite like right.
- I created a profile with the desired area I want to cut out as lines
- Edit wall type
- Edit construction structure
- View: section
- Reveal
- Add, and set to my profile
- Adjust offset so it centers on my wall.

However, I doesn't seem to cut away the wall foundation.
I thought revit can only handle voids in it's native element.




Hmmmm.
I just tried again, as Steve Mintz described using a Generic Model as a Structural Foundation.
It drew my sweep as a profile then selected it.
So this gives me decent global control as I can change the shape of the void in multiple instances of my wall foundations.

However, it seems that for each segment of wall foundation, I end up having to create a new in place model, draw in the path, select the profile, etc.

While not too bad if i've only got a couple walls, but if we start talking 20+ walls, it's going to get a bit tedious.

Any thoughts on a simpler way of doing this?

also, I can't seem to clean up the corners quite right.

Sorry guys for being so "questiony"
