walls attached to floors and cutting problem

[Justin Marchiel]

i am having trouble getting to have my walls and floor attaching together. in the attached image the one on the right has 2 walls ontop of each other but the floor cuts out the wall entirely, and the one on the left the wall is full height, but i can get the floor sheathing to run out to the wall sheathing.

Has anyone figured out how to get this to work correctly? I like to use the the 2 wall method, but seems to be the worst option of the 2.

can anyone help?

Thanks

Justin

Are you trying to let the wall pass beside the floor slab uninterrupted? To be able to stretch the sheating down, you have to edit the wall type and unlock the layers in the preview window. In the wall type properties dialog, preview the wall in section, select the bottom of the layer you want to be able to stretch and unlock the padlock icon. Then in your model, you'll be able to stretch that layer. You can also do multiple layers.

You could do 2 separate walls as on the left, but have the lower wall extend all the way up to the second floor level. When you draw the second floor, sketch the line along the wall's outer face of core. Then if you join geometry it should still have the sheathing running up the outside. If you then join geometry of the 2 walls it will make the sheathing appear to run continuous all the way up.

However if this is wood framing, and you want to model it as it would be built (lower wall = height of studs w/ top plate), then the floor framing on top of that, and then the upper wall on top of the 2nd floor framing, then it would end up looking like your pic on the left, unless you unlock the sheathing layers as was mentioned and drag those up to cover the gap.

Thanks! This was about to drive me crazy!

We never bother doing two walls for wood framing. Even in the last 4 story job I did the walls ran full height. It saves time and reduces constraint and alignment errors. The only advantage I could see in doing it as 2 separate walls is if you are tring to do framing plans and take offs, which we all know Revit isn't good with.

how do you handle not having the floor sheathing run out to the wall sheathing then?

I didn't realize that you could unlock the layers and drag them down (as described above). with out playing with it would someone know if this would be by instance, or globally for that wall family?

There is a "mistake" with the floor sheathing in the sample templates.
Think about it. They have the floor sheathing set as "Substrate". It isn't a substrate. It is structural since the wall above it sits on it. As soon as you make that change - the walls work perfectly.

I've discussed this with adsk - maybe we'll see an update to the default templates so this doesn't confuse so many people right out of the gate.

i will have to give this a try. I am still fairly new to revit, so i am not totally thinking in revit construction (coming from ADT)

thanks.

Once you unlock them, then you'll be able to modify any instance on it's own. See attached image for the unlocking process.
