What is GDNT Different between 1st angle & 3rd angle

Question

Accepted Answer

GD&T stands for Geometric Dimensioning and Tolerancing. The difference between 1st angle and 3rd angle projection is the placement of the object in relation to the views.

GD&T is a system for defining and communicating engineering tolerances
1st angle projection places the object in the first quadrant, while 3rd angle projection places the object in the third quadrant
In 1st angle projection, the top view is below the front view, while in 3rd angle projection, the top view is above the front view

Accepted Answer

GDNT is geometrical dimensional tolerance it use good ginishing & reduce cost
1 st angle is front view and top view & 3rd angle is top view & front view
