3 Walls, 1 Door

[Matt Brennan]

What do you do if you have a situation when you want to place a furring wall on each side of a structural wall but keep each wall as separate entity? Revit Building handles this very well. The only issue you might run into is when you want to place a door or a window in it. Usually the door will attach it self to one of the walls and then you will have to create an opening in each of the walls to fix the problem. This can be very time consuming in the long run especially if you have 20, 30, 40 doors to do. You can always use groups for this but that again can be time consuming plus you can achieve some unexpected results.

If you haven’t played around with the “join geometry” tool, this is something you might want to explore more in depth. You can use this tool to join all 3 walls together. After joining all 3 walls, once you place a door in it, the door will cut all 3 walls.

I stumbled over this issue the other day and I thought I would post it for the AUGI user benefit. This might already be posted here on AUGI but I think it is a tool that we need to keep reminding ourselves with. I hope this has answered some questions that some of you might have had.

If you have any further questions, do not hesitate to ask. Enjoy...

Great Tip!!! I am just about to do the same thing. I have a walk-out to complete a project. Adding stone to the exterior & a frame wall to the interior .This will come in handy!

We do it this way as well. The one issue we ran into concerns the 'Room Bounding' parameter for the walls. This seems to create some issues with areas and room tags. I will try to dig up what exactly happened but, as you could imagine, joining two or more walls that are 'Room Bounding' causes a little confusion for Revit.

Hey there,

This feature was introduced in Version 6 or 6.1 and is great. But what you may not know is that it also works for walls that are spaced up to 6" apart.

This comes in handy sometimes, especially when you have a new wall next to an existing wall during a remodel project and you have a 2" or 3" gap or separation. (I have run into this when adding an addition to a building which wasn't exactly "square" due to poor layout. I had my new wall running "normal" to all of the other walls in the new addition and had a small tapered gap between the new and existing buildings. This way, all of my doors and openings remained parametric.

Keep those tips coming!

Another issue is with the doors or windows families that contains voids.
If you want a "special" opening you must erase the standard opening and use voids because it's impossible to have more than one opening in a family.
In this case, if you use such a family, revit doesn't cut the joined wall.

In this case, if you use such a family, revit doesn't cut the joined wall.

I've done some another tests.
This can be corrected if you extend the voids OUTSIDE of the primary wall.
- Place a reference plane outside.
- constrains this plane with a dimension (you can use parameters to adapt to the thickness of the other walls.)
- Lock the void to this plane.

It works fine. All the walls are cuted.
