Viewing levels in 3d view from same position
I am building a floorplan of my house for a Home Assistant floorplan implementation.

There are 2 floors and this requires a photo of each. For the ground floor, I created a photo using aerial view (a little to the side to show the 3d view of the house) and stored the point of view. The idea was that the first floor photo could be superimposed over the ground floor photo to give the realism of 2 floors of a house in proportion with each other.

When I came create the photo for the first floor from the stored point of view, it was clear that that stored point of view was relative to the position of the, now active, first floor. I believe it is possible associated with the floor of that level itself (although I may be wrong about that - hard to tell). This meant that the image was completely out of line with the top of the ground floor.

I cannot work out how to ensure that the point of view is actually at a fixed x/y/z/tilt angle for both photos. Simply moving the point of view up and down is no good as the relative position means it does not move in relation to the photo of the ground floor. I hope I have explained this as it is difficult to put into words but the simplistic description is I cannot get 2 level photos from the same position and angle.

I had to create some photos png images as links (not sure I understood the http link for an image.....) so I am afraid you would have to look at them this way but they show 4 photos, supposedly from the same position although the last is after reselecting the stored pov. If you look at the extension at the back of the house, you can see that the image places the ground floor in a different position and magnification each time, so I cannot created the first floor in the correct position, sitting on top of the ground floor.
