Whichever floor you work on, you also work on that floor in perspective. In the program, you will see a 4-pane tile in the upper right section. (I'm uploading the image as an attachment.) The first box; It shows all the architectural and static drawings or the drawings of the mode you are working in. The second box; If there is a selected object, it shows it, otherwise when you click on the box, an image will not appear on the screen. The third box; Shows the floor you are currently working on. The fourth box; Makes the perspective window full screen. While working in architectural mode, I think you will get the answer to your question if you activate the boxes one and three that I marked in the picture. Good work
