ENGINEERING FABRICATION, CONSTRUCTION,
AND ARCHITECTURAL DRAWINGS
This chapter describes the basic symbology used in the dimensions and tolerances
of engineering fabrication, construction, and architectural drawings. Knowledge
of this information will make these types of prints easier to read and understand.
EO 1.1
STATE the purpose of engineering fabrication, construction,
and architectural drawings.
EO 1.2
Given an engineering fabrication, construction, or architectural
drawing, DETERMINE the specified dimensions of an object.
EO 1.3
Given an engineering fabrication, construction, or architectural
drawing,
DETERMINE
the
maximum
and
minimum
dimensions or location of an object or feature from the stated
drawing tolerance.
Introduction
This chapter will describe engineering fabrication, construction, and architectural drawings.
These three types of drawings represent the category of drawings commonly referred to as
blueprints. Fabrication, construction, and architectural drawings differ from P&IDs, electrical
prints, and logic diagrams in that they are drawn to scale and provide the component's physical
dimensions so that the part, component, or structure can be manufactured or assembled.
Although fabrication and construction drawings are presented as separate categories, both supply
information about the manufacture or assembly of a component or structure. The only real
difference between the two is the subject matter. A fabrication drawing provides information
on how a single part is machined or fabricated in a machine shop, whereas a construction
drawing provides the construction or assembly of large multi-component structures or systems.
Fabrication drawings, also called machine drawings, are principally found in and around
machine and fabrication shops where the actual machine work is performed. The drawing
usually depicts the part or component as an orthographic projection (see module 1 for
definition) with each view containing the necessary dimensions. Figure 1 is an example of a
fabrication drawing. In this case, the drawing is a centering rest that is used to support material
as it is being machined.
