[In order to provide a logical way to organize and refer to the drawings a system of
numbering must be established. There are several ways to do this. The simplest method
uses single numbers beginning with 1.
, -For larger drawing sets where consultants are involved, numbers are preceded with a
capital letter designating the discipline involved. "FP" is used for fire protection.
-For large projects the drawings within each discipline can be grouped; for example:
floor plans could be group 1, The group number is followed by a decimal point then the
sequential numbers start with "1", example FP2.1 (fire protection group 2 page 1)
-For projects in a high rise with different sections the number is proceeded with the floor
number. For example 5FP4.1 (5th floor fire protection group 4 page 1).]
Which method of information gathering entails using photographs from different angles
to create a three-dimensional model? - Answers- Convergent photogrammetry
[Source: Interior Design Reference Manual, 6th Edition, Measurement and Drafting
Convergent photogrammetry entails using photographs from different angles to create a
three-dimensional model. This process takes a long time but is relatively inexpensive.
Stereophotogrammetry entails superimposing one photograph of a building over
another, creating an image that can easily be converted into a 3-D depiction. This
process requires special software and equipment.
Rectified photography is a technique for producing scalable images of building façades.
Orthophotography is a technique for aggregating digital photographs into a single,
three-dimensional image, using sophisticated computer programs.]
When creating a drawing that will be used for reproduction in a magazine, it is best to
use - Answers- a graphic scale
[Magazines and other publications typically reduce original drawings to fit the format of
the publication. Only a graphic scale would enlarge and reduce in the same proportion
as the drawing.]
