Collection of 2D drawings which enables you to have a complete representation of an object is called orthographic projection. Collection of 2D drawings consist of six orthographic views Top, Bottom, Right, Left, Front and Back view also called as six principle views. From these six orthographic views front, right side and top view are most commonly used to represent the orthographic projection of an object.

In First angle projection, the object lies in between observer and plane of projection. Lines on an engineering drawing signify more than just the geometry of the object and it is. Between the observer and object plane of projection lies.

The orthographic projection system is used to represent a 3D object in a 2D plane. The orthographic projection system utilizes parallel lines, to project 3D object views onto a 2D plane. According to the rule of orthographic projection. To draw a projection view of a 3D object on a 2D Plane. The horizontal plane is rotated in the clockwise direction.

This is one of the most common topics of discussion in the community of mechanical engineers and designers alike. Ask any professional with a hands-on experience of design and tools, he or she will say this is nothing but the means of representing three-dimensional objects in two dimensions. First and third angle projection are nothing but ways of describing what an object looks like from different directions. This is called orthographic projection and orthographic is nothing but engineering drawings or plan views. This is one of the most common methods used to obtain engineering drawings, mostly for orthographic projections. Orthographic projection is a graphical method used to represent three-dimensional structures or objects into different perspective projection images called views.

First Angle Projection Vs Third Angle Projection

First angle projection and third angle projection are the vocabularies of technical drawings. These are the latest standards used in engineering drawings to communicate design intent among different stockholders. In simple words, 1st angle projection and 3rd angle projection are the types of Orthographic Projection system which is used to project three-dimension objects into two-dimensional projection view. Orthographic projection works on the principle of projecting views to imaginary planes which are called reference planes. In 2D drafting, you can have two planes perpendicular to each other and normal to the human eye. One plane is in the X- Direction and the other is in Y Direction. These two reference planes, when placed at the perpendicular, creates a four-quadrant where you can place a 3D object to project views.

Every engineer must know how to read engineering drawings and the most integral part of this is knowing the difference between first and third angle projection. A collection of 2D drawings can be used to represent a 3D object in orthographic projection and consists of six orthographic views Top, Bottom, Right, Left, Front and Back view also known as six principle views. Out of these six, front, right side and top view are the most commonly used ones. But how do you get these orthographic views from a 3D object? We essentially have two main types of projection techniques, the First angle projection, and the Third angle projection.

First angle projection and Third angle projection are two different methods of creating a 2D drawing of a 3D part. First Angle Projection is commonly used in all countries other than United States. It is mainly used in Europe and Asia countries. Following table describes what is the difference between or comparison between First Angle Projection vs Third Angle projection. Following are the details description of first angle projection vs third angle projection given in text note from above table for better readability.

Сьюзан стукнула кулаком по столу: - Нам необходимо это кольцо. Ведь на нем - единственный экземпляр ключа! - Теперь она понимала, что нет никакой Северной Дакоты, как нет и копии ключа. Даже если АНБ расскажет о ТРАНСТЕКСТЕ, Танкадо им уже ничем не поможет.

 - Она улыбнулась и села напротив шефа. Стратмор был крупным кряжистым мужчиной, чье невыразительное лицо скрывало присущие ему решительность, настойчивость и неизменное стремление к совершенству. Серые глаза светились уверенностью, с которой сочеталась профессиональная скрытность, но сегодня в них проглядывали беспокойство и нерешительность. - У вас испуганный вид, - сказала Сьюзан.

Беккер наклонил голову и открыл дроссель до конца. Веспа шла с предельной скоростью. Прикинув, что такси развивает миль восемьдесят - чуть ли не вдвое больше его скорости, - он сосредоточил все внимание на трех ангарах впереди.

What is The Difference Between First And Third Angle Projection? A Mechanical Engineer Explains

What is Third Angle Projection?

 Сюда, мистер Беккер. Быстрее. Беккер повернулся и побежал, но успел сделать только один шаг. Мужчина выхватил оружие и выстрелил. Острая боль обожгла грудь Беккера и ударила в мозг.

Брови его поползли вверх. Он был потрясен.

 Согласен, - сказал Джабба.  - Этот парень был диссидентом, но диссидентом, сохранившим совесть. Одно дело - заставить нас рассказать про ТРАНСТЕКСТ, и совершенно другое - раскрыть все государственные секреты.

Пожав плечами, он подошел к раковине. Раковина была очень грязной, но вода оказалась холодной, и это было приятно. Плеснув водой в глаза, Беккер ощутил, как стягиваются поры. Боль стала утихать, туман перед глазами постепенно таял.

Уничтожение ТРАНСТЕКСТА. Уже несколько лет Танкадо пытался рассказать миру о ТРАНСТЕКСТЕ, но ему никто не хотел верить. Поэтому он решил уничтожить это чудовище в одиночку. Он до самой смерти боролся за то, во что верил, - за право личности на неприкосновенность частной жизни. Внизу по-прежнему завывала сирена.

First Angle and Third Angle are two methods orthographic projection used in technical drawing and normally comprises the three views perspectives : front, top and side.
