WEEK 4
‘Scale, annotation & working drawing conventions’ activity!
!
Hoi Yin Ho, 662109 ! Below are some sections (on the left) and symbols (on the right) that represent the three basic building materials in architectural drawings.!
The importance of scale is to allow ideas to be shown in realistic ways by drawings with scales. Using larger scale, we can see the overview of a large object in real life in a sheet of paper. Using a smaller scale, we can see the detailed views of particular points that we want to focus on.!
By reading the drawings, I can have a very clear image about how the constructing materials are put into pieces to form the actual building.!
! !
After reading the drawing sets, I recognise that the preferred unit is in millimetres (mm).! The drawings of the pavilion has a range of scales such as 1:100, 1:50, 1:20. For the details of the joints and roof, there are scales like 1:5 and 1:2.!
! ! ! ! ! ! ! ! ! ! ! ! ! ! !
!
Just looking at the building at the site will not allow us to study about the joints and what is within the walls.!
! ! ! ! ! ! ! ! ! ! ! ! !
As the the building is shrunken into smaller scales in the drawing, we can see the building as a whole. By this we can see the connections between rooms and areas and have an image of how people can operate the site. While as in the site where everything is 1:1, we can experience the building.!
