As an illustration we will create a 3D model of a garage with tilted entry from the street to the second floor.
1. Let's begin by drawing the first floor
2. Draw the floor of the second stage. The floor can be created by adding object "Box".
If height of the wall is 3 meters, then the floor should be installed on 3 meters, because this is zero level for the second stage. Let the floor thickness be 0.5 meters (see the picture below).
*We recommend to block each item to avoid accidental changes.
3. In order to draw a tilted second-floor entry, add object "Tilted surface". height of "Tilted surface" should be 3.5 meters (3m wall height + 0.5m floor thickness).
4. Draw walls on the second floor. Installation height is 3.5 meters (3m first-floor wall height + 0.5 m floor thickness).
5. You should remember, that for the first floor parameter L must be 0 and camera installation height must be below 3 meters. In this case, for the second floor parameter L is 3.5 meters (3m wall height + 0.5m floor thickness).
1 floor:
2 floor:
On the "Camera installation Drawing" tab you can set the parameter L by raising the grey end-point to the floor level of the second floor.
