Hi testu, and welcome to RFO (and Revit!)
I'm not sure what you mean when you say "walled door", but I'm guessing you mean there is currently a door in one location that you want to remove and repair the hole.
Then you want a new door in the location to the left.
You'll want to do this using Revit's Phases
The Out of the Box template comes with an Existing Phase and a New Construction Phase.
You do NOT need a Demo Phase, although you will want a Demolition VIEW (Read about Phase Filters)

Model the Walls and the existing Door in the Existing Phase
Then in the New Phase, use the Demolish Tool (the sledge hammer in the Modify Tab...Geometry panel) click on the Door with the hammer, and it will disappear from the New Construction View. The hole will be filled in with the same Wall Type as the original Wall.
The Door will remain as it was in the Existing View and, if your Views and Phase Filters were set up correctly, it will show as dashed in the Demolition View.

Then you'll need to place a new (different) Door in the New Construction View. You cannot just move the original Door

Hope that helps

Hi, and thank you for the response.
Actually I do not know how to explain the "walled door": I've tried a better translation, but I could not find it.
Lets say previously there was door connecting thekitchen with the living room, but then the door was demolished, and the hole was filled by 8 centimeters bricks.


So, now there is a beam on the top of the hole, which keep the bricks in place.


Now, for the project I'd like to demolish the wall to reopen the way from the kitchen to the living room.


I think a good solution in Revit is draw the first 30 cm wall, then make a 10 cm wall without the "join status" option active, then draw again at 30 cm wall.
Later, during the demolition phase, it will be demolished for the high demand for the new door.


This is my method, but I do not know if there are better solutions ..


Thank you again

So essentially you have two different types of walls, so you draw them that way. You can either; Draw one wall then draw the other in the Existing Phase and then use the Cut command to cut one wall out of the other; or you can edit the profile of one wall to the size of the other one and then draw the other wall in the opening.

I use this method if I want to demo a door but leave an opening instead of Revit adding in an in-fill wall.

That makes some sense. The opening that use to have a door was infilled with a wall. Don't worry about the door, that's long gone by the sounds of it.

Edit the profile of the overall larger wall and put an opening where the door use to be (or the extent of the infill). Then model another wall (the infill) in the opening which can be demolished.

Thanks both
