Fit it to your terrace: drag the glass room to move it anywhere on the ground, in any direction. Turn it with the round handle in front of it, or with two fingers on a phone, a full 360°. Pinch to make it bigger or smaller in the photo. Drag the dotted eye level line to the height the photo was taken from, roughly where the horizon or the far end of the garden sits, so you look onto the roof at the right angle. Type your real measurements on the right; the picture and the price follow them. Your photo stays on your device unless you send your design to 365.
