Thickened Slab Edge

[sjsl]

Curious, how would any of you create a thickened slab edge to be used under interior masonry partitions? Can you create a Family for this? A new footing type perhaps, a sweep under all the partitions or something?

Thanks for sharing, kinda of at a cross roads here.

On a recent project, I just used the regular footing tool. It didn't look 100% correct in section, as the sides of the footing were vertical instead of angled, but it got the point across, and it was MUCH faster than trying to draft filled regions in my sections or trying to apply a sweep to individual walls. The footing from the footing tool also automatically cleaned up nicely with my floor slab.

We use a sweep profile to the underside of the wall. As long as the sweep is the same material as the floor slab you can join geometry and it will work OK.
In section though you will have to use your linework tool to "make invisible" one small join line between the sweep profile and slab.

At least it looks correct.
In an ideal world, it would be nice to have this as a foundation, but that doesn't seem to be the case or even possible, but hey, we get ribbons so all is OK!!

I too, like Andrew, use the floor sweep tool. I have a number of different profiles in the template file to handle the different types of rebates etc.

Nice and easy, gives me a good generic result for the sections & I then only need to add a filled region for the stiffening beams & some notes referring to the engineers design etc & its a done deal.

Cheers,

But, what if the floor is sloped..?

I had not realized until now that I cannot create a Floor Slab Edge on a sloped side.

What I am trying to do is create a 2' tall concrete bumper along my sloped parking garage walls... ANY IDEAS..??

Make sure your floor is flat before applying the slab edge. Once applied, you can edit your floor and make it slope again. The slab edge will follow.

That is great to know. Thanks..!


IF you have a second to look,,, is that how you would approach the attached condition..??

(Trying to follow slope of floor with short conc. wall...)

You can make it as two separated walls (the CMU as one and the concrete as the other) and edit their profile in elevation to follow the sloped slab. Then join them...

Another good answer...

Unfortunately, I have about 200 walls in the floor plan all trying to follow the slopes of 3 or 4 large slabs... That is why I was thinking Floor Slab Edge... But of course I do not have slab edges beneath all my walls... ugh.

I guess I am looking at a Line Based model family..?

All these options seem more tedious than Revit usually requires... hmm.

There are always other options...

You could even create the concrete wall as a railing, that can be hosted by the floor and will fix itself whenever the floor slope changes (if ever). Line based families wouldn't trim properly when changing orientation.

Another option you may want to consider is to copy your slabs 2 feet above the original ones and simply attach the base of your concrete walls to the slab below and attach the top of your concrete walls to the slab above. All your 200 Walls would be easily controlled by those extra slabs. To get rid of the extra slabs and avoid them showing in your drawings, just hide it. It can be easily achieved by creating two phases before the phases of your project. Call it slab creation and the other slab demolition. Set the extra slabs as created under the phase slab creation and demolished under the phase slab demolition. You wouldn't see it in your project because the extra slabs were demolished even before you project started... Got it?

I did think of the Railing tool, and still may try that one out...
But phasing of "control" slabs is just darn sexy... there has to be a catch.

First of all, the slab thickness with be void between my two vertical walls... I guess I can make the control slab paper thin...

Then, I will have to duplicate the wall count... No big deal if I align lock them together...

CAN you think of anything adverse that may occur with this "before const" phasing..? Like weird clean up issues down the road...? It seems pretty clean in testing...

Excellent tips... and right on time. THANKS..!

(I owe you one if you're ever in town with a Revit prob... haha)

No. I think the best then would have two control slabs with thickness and right on top of each other but sharing the same edge (that will be exactly where your walls - the concrete one from the bottom and the CMU one from the top - will be attached). So the top of the concrete wall will be attached to the bottom of the upper control slab. And the base of your CMU wall will be attached to the top of your lower control slab. Doing this, both will share the exact sane edge. No voids in between.

Don't be concerned about the phase thing. Remember: These control slabs won't even exist anymore in your project when your new elements start to be drawn...

We have been using phases before the project to create legends for long time....

Why not! Who knows... ;) Thanks!

Works like a symphony... Thanks again.

It may be more technical than using the Railing tool, but it is also more effective as I do not have to worry about the mating of Railing objects and Wall objects...

I have used phasing to hide things before, but never to control my geometry.
Excellent technique.
