Creating door openings in 3D not working as intended

SketchUp
1

Hello!
I’ve been working on my first floor plan in sketchup, now want to make it 3D. I’ve been following this YT guide: SketchUp Tutorial – How To Turn 2D Floor Plans into 3D Models (in 5 EASY steps) - YouTube.

In section 3, where he adds door openings, he pushes the doors from below the floor plan after creating a rectangle over the opening. When I do so, however, it doesn’t create an opening, just shows lines for where the door should be.

I can still remove these myself and create the opening that way, but it’s not efficient. I wonder what’s wrong in my plan to cause this problem. I’ll add that file to this topic as well.

I hope the picture adds correctly, but on the right here you can see the outline of where the door should be, this is what happens after pushing the rectangle I create from underneath the floor plan:

hello,
that’s because you don’t have a face on ground level at the door location in the active context. You’ll feel like you’re going to push/pull one because there is a face on that spot that lies in the locked object but it will push/pull a vertical face instead.

Here’s what it looks like after deleting every faces in the locked imported plan, looking from below :

I’m not sure about the tutorial you’re working with. It has a tricky approach that can lead to mistakes

Check Scene 1 of the following SU file for a simple way to open such a door.

Check Scene 2 for a potential problem.
