So in this assignment we are supposed to draw a sectional drawing of our house model that we previously made. The floor plan was given by the lecturers already but the furnitures we have to match it with the ones that we made. 
There are 2 drawings that we had to do, first is section b-b and section c-c, that one we had to make it with pencil on cartridge paper only, but the section a-a and d-d we need to draw it on tracing paper with pen.
