With centre P and radius PQ, draw an arc intersecting AB produced at R. AR is equal to the diagonal length of the pentagon. 5. With centres A and B and radii AR and AB respectively draw arcs intersecting at ...
Role of Engineering Drawing: The engineering drawing subject is designed to impart the following skills: 1. Ability to read and prepare engineering drawings. 2. Ability to make free - hand sketching of objects. 3. Power to imagine, analyze and communicate. 4. Capacity to understand other subjects.
used for preparation of drawings. • Standards – set of rules for preparation of technical drawings. Conventions – commonly accepted practices in technical drawings. • Tools – devices used to create technical drawings and models. • Applications – the various uses for technical drawings.
The purpose of this guide is to give you the basics of engineering sketching and drawing. We will treat “sketching” and “drawing” as one. “Sketching” generally means freehand drawing. “Drawing” usually means using drawing instruments, from compasses to computers to bring precision to the drawings. This is just an introduction.
Engineering Drawing Module No. 2 - Free download as PDF File (.pdf), Text File (.txt) or read online for free. The document provides an overview of basic instruments used for engineering drawing, including T-squares, compasses, protractors, templates, and pencils of varying hardness.
The document provides answers to short questions about engineering drawing topics like development of solids, isometric views, orthographic projections, sectioning, dimensioning, and the basic elements and types of lines used.
Set the compass to radius B-1 and draw two arcs, with Y as center. Set the compass to radius A1, and draw two arcs with X as center. Intersection points of the two arcs are points on the ellipse. Repeat this step for all the remaining points. Use the French curve to connect the points, thus drawing the ellipse.
