EXPLORE A CONTROLLED DRAWING
Read the component in layers.
Separate the connection interfaces, material information and drawing reference to see what each contributes.
Interfaces describe how components meet.
A controlled drawing can define the interfaces between the fitting and adjoining pipework or an assembly. The family name explains the general function; it may not describe every interface detail.
An outline does not identify the material.
The drawing and its referenced specifications can define a material designation, condition and acceptance requirements. The shape of a component alone does not establish those material details.
The drawing issue is part of its meaning.
A drawing number identifies the reference, and the revision identifies its issue. Different issues may define different geometry, materials or acceptance details.
Illustrative geometry only. These layers teach how a drawing is read; they do not define installation dimensions, tolerances or a supplied component.
