Descriptive Geometry - A Paper Roof!
Alexandru writes:
Part of my classes are about the technical issues of architecture, and one of those is called "Geometrie descriptiva" , something I would translate as "Descriptive geometry", with specific geometrical problems to be solved. Last week we have been learning about roofs and their elements. It may sound strange, but getting the right slopes and having everything in place in the correct way is sometimes very tricky. especially as we use rather utopian and atypical examples of buildings, just for developing the necessary skills and, very importantly, the 3D imagination.
On Wednesday we will have an exam, with such an example of a roof to be allowed at the exam, we have to create a scale model of a roof we have solved during a previous exam. I decided to make this a bit more interesting and I started thinking about a scale model out of...paper!

So, I made all the drawings using the AutoCAD software, as you can see in the picture here named "Macheta Acoperis" - Macheta is the Romanian word for scale model, and Acoperis means roof.

It was quite an effort but I thought it would be an interesting experience to print a scale model and then put it together into 3D shapes that fitted perfectly. So I printed the shapes, cut them, bent them and glued each to a piece of foam board.

The other photos show steps of the making of the roof. I also used some adhesive tape and 2 extra small pieces of foam board - these represent walls from neighbouring houses, where the roof must take a particular shape to prevent snow and rain from affecting these walls. In the centre of the structure, you can see the inner yard or patio of the house, with 4 slopes converging into it.

I hope you enjoy this story and the photos, it was really fun for me to create it - the paper roof!
