EXTERNAL RENDERING

finally, how can i make this kind of roof, industrial type?

is it possible to add context only as a flat and then enlarged photograph?

ok thank you, and how can i add external floor ?

1 To show the external wall, click "view" on the top and then untick the "hide wall" option. 2. To move the camera (where you stand), you could either use the shortcut keys (press the A D W S Q E to move left/right/forward/backward/upper/lower)， or directly drag the little camera from the upper right corner viewport.
