4. When it comes to the futuristic version we can use the same scene as a starting point and simply delete the pillars and raised platforms. I decided to raise part of the floor near the edges to create a slightly different feel to this scene but the lower level still corresponds with the floor in the previous scene. The next step was to create some basic cylinders that will represent the pipes that run along the walls (see image below).

Apart from the two ceiling mounted ones these are placed just off the walls so we can build some wall supports that hold them in place. To do this we first position the pipes and then using a line tool we simply trace around them to create the brackets as seen in the image below.
