Final Answer:
The basic dimensioning system used in auto body drafting is the "Unilateral System."
Step-by-step explanation:
The Unilateral System is the fundamental dimensioning approach employed in auto body drafting. This system involves placing dimensions on one side of the object or feature, typically the left, to simplify the reading and interpretation of the drawing.
In auto body drafting, precision and clarity are essential, and the Unilateral System helps achieve this by reducing visual clutter and confusion.
This dimensioning method is particularly useful in conveying critical measurements for the fabrication and assembly of auto body components.
By adhering to the Unilateral System, drafters ensure that dimension lines and numerical values are presented in a logical and unambiguous manner, streamlining the communication of design specifications.
In summary, the basic dimensioning system used in auto body drafting is the Unilateral System, chosen for its effectiveness in providing clear and concise dimensional information to facilitate the manufacturing and assembly processes.
