Wall below the door

[m.kopaniaAQZ65]

Hi,

I have a situation linke that. I have some construction slab. Than i have walls situated on this floor(1). On this structural floor there are some finishing layer(2). When I put any doors  in teh wall, below there still remains part of the wall(3). How to remove it?

When I add additional void in the family, below the doors, and then try to make cut between  the wall and doors, revit says it can't do it.

When I extend door void in the family, Revit set the lowest point of this void as a reference level and the whole doors goes up.

Any suggestions?

have you tried making an additional void extrusion constrained to the door width and the wall thickness and then have its depth on a parameter. set the default on it so that it is above the floor level and can cut the family host wall, but then when it is in the project you can set the void so it cuts the wall below the door.

Sounds like you want to utilize Layer Extension. 

Here's how:

Hi,

Have you tried using the join command to join the floor and the wall?

1. Add a ref plane in the family below the level
2. Add an instance dim parameter to control the distance from the level to the ref plane
3. Constrain the bottom of the cut opening to the ref plane
4. In project, enter a value for the parameter to cut wall below the door. When not needed, keep it = 0.

Yep, that's correct. Except, that you need also to add ref plane at reference level and set it to define origine.
Otherwise revit will set origin at this new ref plane below, and the whole doors will go up according to the value of this new parameter.
