Every beginning is difficult, but that rule doesn’t have to apply when it comes to SketchUp. In order to prove it, I will try my best to show you how to quickly and efficiently create such an object in the following lessons. In doing so, I will pay special attention to the elements found in the interior, because I am sure that you will find it very interesting.

To that end, I have already prepared a simple sketch that clearly shows the basic dimensions of the new building, as well as the positions of future openings and connections to other rooms. I believe you now have a clear idea of what I want to achieve, so I can go back to SketchUp and start a new project.

Drawing a new object usually starts with the walls, so I will immediately place the elements that will be used for their modeling. To that end, I will use the Rectangle function and select the coordinate origin as the first point. After that, I can move the cursor up and to the right, and if you pay attention to the lower right corner of the screen, you will notice that the data representing the dimensions of the future rectangle appear in it. The first value represents the distance in the horizontal (red) direction, and the second refers to the vertical, which in this case is marked in green. I have the exact dimensions, so I will enter them via the keyboard in the following form: 16′, 30′. After that, all I have to do is complete the process with Enter and check what I have achieved.

Due to the difference in scale, a relatively small rectangle appeared on my screen, but this can be easily corrected by using the wheel, ie. by activating the Zoom function. A similar effect can be achieved by using the Zoom Extents function, and it only depends on you which option you choose.

The lines that make up this rectangle represent the inner edges of the future room, which means that the thickness of the walls should be defined so that they are placed outside this area. This is most easily achieved by using the Offset function because it allows me to add new elements in one stroke that will be placed at a precise distance and at the same time follow the existing form. To that end, I need to place the cursor over the corresponding element and select it by pressing the left mouse button, so that I can then select the side and enter the desired distance. As you yourself can conclude, at this moment it does not matter where this red dot is located because by moving the cursor the position of the new element can be easily selected. This time I will use the opportunity to determine its final position in numerical form, so I will enter the number 9 on the keyboard and finally press Enter.

That will be enough for the elements that represent the edges of the future walls to appear on the screen, so I could easily add a couple of transverse lines that mark the position of the openings and create a spatial structure in one stroke. Although this is a perfectly legitimate procedure, I prefer to define all the walls first and then create openings in them, so I will undo this step and go back to basics.
