Thickened Slab, Grade Beams

[PitMan71]

Construction here is mostly block up slab. I have been successful in creating the exterior footings and CMU walls. now I am trying to figure out how to do a brace beam OR thickened slab under a load bearing wall. I usually do 16wx16h (bottom to top of slab). I have tried the slab footing tool, but it insists on pushing the footing down level with exterior footing and adding a stem wall, which I don't want. I want the footing to be poured with the slab and thicker under load bearing walls and in other locations (not always under a wall) where I want an interior footing. Anyway, I am sure that this can be done, just not sure of how.

 

Thanks

Where would this type of footing be, when not under a wall?  

 

Any wall type can be made to have footings under them.

When not under a wall, or if irregularly shaped, use a pier or concrete pad.  I normally have it 12" high at -4" (below the concrete slab, which nets 16" overall.)

These are both great ideas. I have tried both..... When you add either, how do you get the footing layers to show on the foundation plan?

 

Also, how do you setup the invisible wall not to cut out the ceiling drywall where it connects?

 

Thanks

Make the invisible wall have a railing attribute.  Put the footing on the footing layer.  This should solve both of your questions.

Gotcha.

 

Thanks

Okay all. I have figured out the best way to accomplish this now..... One thing I can't figure out... How do you get the footings to display on the foundation plan from these walls? Footing layer is on for level "0" but footings from floor walls are not showing like the perimeter footings.

 

Thanks

You can do that by setting up a new reference display layer set, turn off all layers in this set that you don't want.  Set up the display for the footings, and reference walls on a different floor to display at the same time.
