This is a personal DIY project where I would like to take down completely some interior walls. I've done measurements all around, attic, crawlspace inside/outside, and openings as well.
The house is a rambler style 1956 build, gable roof, one story level simple as is.
Edit/Update: The roof has rafters.
The walls I like to remove are red colored on the 3D model, and marked on the drawing.
The model displays rafters, ceiling joists, posts/pier concrete positions, everything possible probably to know and judge if the walls are bearing or not.
All dimensions are ± 1.5 inches error and can be seen on the below image and also you can visualize the house as a 3D model on your browser to the following link:
