The second floor can be created most easily by copying the existing ceiling. So I’ll run the appropriate command, select this element and set it to a slightly higher height.

After that I could zoom in on one of the edges and measure the thickness of the board. For these purposes, I will use the Distance function and simply select the points located on the opposite edges. If we keep in mind that it should serve as the floor of the first floor, we will easily come to the conclusion that it is too thin. To solve this problem, I will simply add two more elements like this using the Copy command and place them one below the other. After that I can run the Union command, select all three plates and make them a single element. If I check its dimensions again, a result will appear on the screen that is much more favorable than the one at the beginning of this lesson.

Since I’ve successfully created a new element, it wouldn’t hurt to place it on the appropriate Layer. To that end, I’m going to open the layers box and increase this list by one more item. This time I’ll enter 3D-Slab2 for the Layer name and simply skip its activation. Its status doesn’t matter to me at this point, because I just want to change the location of this board anyway. This can be achieved most easily by using the Quick Properties function, so I will first select this element, enter the appropriate shortcut and from the list, instead of 3D-Ceiling1, select 3D-Slab2.

In the end, I still need to place this plate in its right position, so I will start the Move command, select the appropriate element and choose its upper corner as a reference point. After that, it will not be difficult for me to click on the point located on the upper edge of the wall and thus complete this operation.
