As an interior design student, I am also learning on how to work with softwares. One of them is Sketchup. The pictures below are of the first sample plan that I got to work on just to understand the basics and am still understanding as there is a lot to learn.
For me, introduction to this software was something very exciting because it was the first software that I got to know related to designing. To see a 2D design come to life is something really really cool! And that too with endless possibilities, from selection of bricks to fabrics, colors, finishes and so much more. There is a lot one can experiment in with this software, if ample time is given.
Hope to share more stuff with you guys. :)
