WAll and floor join

[annie123]

We need to create a walls at level 1 which continuous till founfation level. But when I place floor and do join geometry to remove the overlapping , the wall gets cut( usual in Revit). is there any way that my wall continue and floor get removed from overlapped portion . pls check the image .

Regards,
Annie

Hey Annie,

As you said this is unusual for Revit, i tried the same thing just now and they joined perfectly as they normally do. Have you done such a simple thing as to try it over again, i can see you're not that far with your project.

The only way this works is if the wall has a higher function than the floor. If you change the function of the slab to Substrate (2) and the wall is a function Structure (1) then the wall will have a higher 'priority' than the floor.
That said, I would probably create the slab using the pick walls option and not model the slab as one piece. This is the way it would be constructed and if you use the pick option the slab edges would update if the wall moved.

The problem with picking the walls in sketch mode is that once you pick one wall to place a sketch line on one side, you can't have another sketch line "hosted" by the wall on the other side. Only automatically placed ceiling objects that go around a wing wall will have sketch lines hosted by both sides of a wall, in my experience.

Simply sketching the perimeter and having the floor cut around interior walls after joining geometry would be a much easier and faster method.

Good call about picking Patrick.
Depending on the number of interior walls and the shapes of these slabs I'd still probably go the multiple slab route for CD's. If sketched using the wall intersections as 'pick points' Revit will still set up a fairly reliable automatic relationship between the wall and floor. During design I'd probably not even worry about the joining.:beer:

Thanks Dimiti. It solved the issue.

This is the method I would use. In reality this is how it's built. More importantly, if you are using revit to give you concrete volumes, you will get a false value which will include the portion contained within the wall.
Furthermore, if you try to use your rebar tools and place a mat of reo in there, it wont behave as having the slabs separate at the wall will do. Lastly, in reality, there will likely be a turndown of the slab at that wall intersection (either side) onto the footing. Stopping and starting your slab at the wall at ground level in this manner allows you to add an edge thickening at this turndown, rather than having to create a specialised beam family to do the job for you.

[Dimitri Harvalias]

Many different construction methods are possible here that's why I didn't want to get into the actual detailing. A strip footing with stem wall, a slab thickening or a wall poured right to the footing; all might be used and each is as valid as the next. Just proves that there are very few absolutes in Revit, just choices with benefits and drawbacks for each.

OMG, its giving false result.In section floor is cut but when I see 3d view, It is the wall which is cut. why? also after join geometry, volume of wall gets reduced, not of Floor. check the pics.

Yes now try the method of breaking your floor into separate components at the wall face...both of those problems instantly solved..
