This document contains a portfolio of technical drawings and 3D models created by Ryan Leon for personal use in job applications. The portfolio includes drawings for various mechanical parts including a ball joint set, bulge testing parts, button head grip configurations, a calibration load train assembly, a middle plate, and a furnace housing. The drawings provide dimensions, tolerances, notes, and other details needed for manufacturing the parts.
Orthographic projection is a method of representing a 3D object in 2D using multiple views, and is the international language of engineers and designers. It uses top, front and side views, and each projection method has its own symbol - first angle projection shows shadows behind the object, while third angle projection shows shadows in front. Examples are provided to demonstrate orthographic projection.
The document discusses engineering graphics and freehand sketching. It covers curves used in engineering like conics, cycloids, and involutes. It also discusses representing 3D objects through multiple views and developing visualization skills through freehand sketching. The document then provides step-by-step instructions on orthographic projections using first angle projection. It demonstrates drawing front, side, and top views from pictorial presentations. Finally, it outlines the general procedure for freehand sketching orthographic views from an isometric pictorial view.
For those students who start there career in technical line like ITI, Diploma, Engineering of any field this ppt is helpful for them to understand the Engineering Drawing and Its Basic concepts of Orthographics Projection with very good images.
Here are the key line types used in engineering drawings:
1. Visible lines represent edges or surfaces that can be seen.
2. Hidden lines indicate edges that are hidden from view.
3. Center lines mark centers of holes, circles, or axes of symmetry.
4. Dimension lines note the distance between two points.
5. Extension lines extend from the dimension point(s) to the feature.
6. Leaders point to features being dimensioned.
7. Cutting-plane lines indicate where a cross-section is taken.
8. Break lines show only part of an object is drawn for clarity.
The document discusses orthographic projections and sectional orthographic projections. It explains that orthographic projections create 2D representations of 3D objects by projecting lines from edges orthogonal to the projection plane. There are two types of projections: first angle and third angle. The difference between them is the positioning of top, bottom, and side views. Sectional views indicate hollow and solid areas using hatching lines at 45 degrees spaced 0.25 mm apart. The document provides examples of orthographic and sectional orthographic projections of various machine parts.

The document provides information on engineering drawings and technical documentation standards. It discusses the different types of drawings and views used, including orthographic projections, section views, assembly drawings, and pictorial drawings. It also covers important drawing conventions like dimensioning, tolerancing, fits and limits according to British standards like BS 8888. Key information to include on title blocks is also outlined.
This document discusses different types of technical drawing projections used to represent 3D objects in 2D drawings. It describes orthographic projections where projectors are perpendicular to the projection plane, resulting in front, top, and side views of an object. Axonometric projections show an object inclined toward the projection plane in a single view. Multiview projections use front, top, right side, etc. views. First angle and third angle projections determine the placement of views, with first angle being the European standard and third angle being used in America.

Lecture 3 A Isometric And Orthographic Sketching 2009nttf
The document discusses isometric and orthographic sketching techniques used in engineering design. It compares engineering drawings to sketches and explains that sketches are used in early conceptual design while drawings are for final production. Various methods for sketching objects in isometric and orthographic views are presented, including unfolding 3D objects, transferring between views using construction lines, and ordering of drawing different object surfaces. Students are assigned to practice these techniques by sketching a cell phone in isometric and orthographic views.
The document contains instructions and examples for 14 exercises related to orthographic projection. The exercises include identifying views of objects from different angles, matching orthographic drawings to isometric or oblique views, sketching projections of objects, and drawing multi-view orthographic projections of components with dimensions. Solutions or spaces for solutions are provided for each exercise.
This document provides an introduction to different types of technical drawings including orthographic projection views, sectional views, auxiliary views, and isometric drawings. It discusses topics such as dimensioning of radii, holes, countersinks, counterbores, and spot faces. Examples are provided for various types of projection views and isometric drawings. Exercises are included at the end to apply the concepts learned.
Orthographic projections provide 2D views of an object that together accurately represent it. Common views are the front, top, and side. Objects are imagined inside a glass box and each face is projected onto a plane. Dimensions are drawn with thin continuous lines and indicate sizes. Drawings include title blocks with title, author, date, scale, and other information.

An engineering drawing is a type of technical drawing, used to fully and clearly define requirements for engineered items, and is usually created in accordance with standardized conventions for layout, nomenclature, interpretation, appearance size, etc.
Its purpose is to accurately and unambiguously capture all the geometric features of a product or a component. The end goal of an engineering drawing is to convey all the required information that will allow a manufacturer to produce that component.
