Views and Projections – Technically Drawn Pictorial views show a 3-D view of the object of the drawing and are the best views for visualizing an object’s shape Orthographic views show a 2-D view of the object from multiple directions and are the best view for showing detail and measurements
ISO Drawing Questions - Views Hole Callouts | Eng-Tips The ISO standards support three methods of view projection on technical drawings: the first angle, third angle and arrow methods of projection Most people are quite familiar with the first angle and the third angle method but seldom knows about the arrow method, here is the snap shot from Alex's ISO reference guide page 10, I am sure the arrow
First vs Third Angle – Orthographic Views | GD T Basics Orthographic views allow us to represent a 3D object in 2D on a drawing Orthographic views can show us an object viewed from each direction How the views are laid out on a drawing depends on whether 3 rd angle or 1 st angle projection is being used You can tell which angle projection is used by the symbol shown on the drawing
INTERNATIONAL ISO STANDARD 128-30 This part of ISO 128 specifies the general principles for presenting views, applicable to all kinds of technical drawings (mechanical, electrical, architectural, civil engineering, etc ), following the orthographic projection methods specified in ISO 5456-2
ISO 128-34:2001 - Technical drawings — General principles of . . . This part of ISO 128 specifies rules for the presentation of views additional to those of ISO 128-30 and applicable to mechanical engineering drawings that follow the orthographic projection methods specified in ISO 5456-2
3. INTERPRETATION OF DRAWINGS Orthographic projection theory requires that any additional views are horizontally or vertically aligned with the principal (first) view The following figures will be used to show the concept of multi-view drawings based on orthographic projection principles:
Technical Drawing - the OpenScholar Spring 2006 MEC1000 Technical Drawing - D Anderson 4 Drawing Views – Multiview Projection • A view of an object is know technically as a projection • A projection is a view conceived to be drawn or projected on to a plane, known as the plane of projection
