Check blueprints to see if the wall is load-bearing?

Hello!

New member here and also a new homeowner. The house is a 1-story with a basement, built in 1967. I have basically zero experience with construction beyond having sealed a door, spackled, and painted a little.

The previous owner demolished the small bathroom and storage room located to the left of the kitchen on the floor plan to create a larger kitchen. Now we want to demolish at least half of the wall between the kitchen and living room to make space for a larger dining table.

However, I'm not quite sure if the wall is load-bearing or not. Looking at the wall that runs in the middle of the basement, it seems pretty obvious that it's load-bearing as it runs in the middle and looks thicker on the floor plan. What confuses me is that they chose to outline the kitchen's walls on the 1-story as well as the basement's central wall on the section view—have they done this to indicate that these walls have a load-bearing function?

I have requested a structural description, but it is not available.

The truss is designed as a cantilevered framework. If it is indeed built that way, the floor level does not have any load-bearing interior walls. All vertical loads are then on the exterior walls.

The roof truss is designed as a free-spanning framework. If it is indeed built that way, the floor level has no load-bearing interior walls. All vertical load is then on the outer walls.

Thank you for your post! My impression is the same as yours, but it feels better to have it somewhat confirmed by someone knowledgeable. I will check with the neighbors (who live in identical houses) when we move in if they have any insight.
