Isometric and Orthographic Projections, Solid and Plane Geometry, and CAD for Aspiring EngineersBy Helen BroadbentLength11h 24m
About this audiobook
A drawing only works if another engineer can read it without asking you what you meant.
This book teaches you to produce that kind of drawing, starting from line weights and lettering and building through orthographic projection, auxiliary views and sectioning until you can lay out a full detail sheet with confidence. You will construct tangents, ellipses and involute curves by hand, develop sheet-metal patterns from cone and cylinder intersections, dimension a part with proper limits and fits, and represent threads, fasteners and welds the way a shop expects to see them.
The closing chapters move the same skills into 2D CAD and parametric solid modelling, so your screen work carries the same discipline as your board work. Every chapter pairs the underlying projection theory with practice exercises drawn from real drafting office conventions, helping you build the habits that make a drawing unambiguous, manufacturable and easy to check.
What you will learn:
• Select and maintain drawing equipment, lay out a sheet correctly and apply standard line conventions
• Construct plane geometric figures, tangents, ellipses and involute curves accurately by hand
• Project orthographic views and read or complete missing views from a given set
• Create auxiliary and sectional views that reveal true shape and internal detail
• Produce pictorial drawings, including isometric and oblique representations
• Dimension parts with notes, limits, fits and surface texture callouts
• Solve solid geometry problems involving intersections and developments of cones and cylinders
• Represent threads, fasteners and standard components to accepted shop practice
• Prepare assembly drawings and carry the same standards into 2D CAD and parametric solid modelling
For engineering and technical-college students and apprentices starting out in drafting, as well as self-taught makers and technicians who need to read and produce professional engineering drawings. If you are beginning a mechanical, civil or manufacturing course, or preparing for a first drafting role, this book gives you the foundation to work confidently on both the drawing board and the screen.
