Engineering Drawings Skills modules

This group of modules meticulously examines the skills, procedures, and technology associated with Engineering Drawings in the manufacturing process. Each module in this competency group builds on the one before it, giving you confidence as you develop your knowledge in a way that is logical and intuitive.

Blueprint Reading Fundamentals I

Introduction to Blueprints

This module outlines the use, terminology, application, and methods for creating engineering drawings (Estimated completion time: 1.7 hours).

Engineering Drawing Terminology

This module details the words, phrases, lines, shapes, and angles used in the engineering drawing process (Estimated completion time: 1.5 hours).

Engineering Drawing Views

This module shows you how the views on an engineering drawing are arranged and how to draw a three-dimensional object on a two-dimensional surface (Estimated completion time: 1.6 hours).

Engineering Drawing Lines

This module covers the types of lines used in blueprints, the function of line precedence, and interpreting hidden features (Estimated completion time: 1.3 hours).

Dimensions and Tolerances

This module defines the required distances between lines, planes, and points on an object (Estimated completion time: 2.1 hours).

Blueprint Reading Fundamentals II

Geometric Dimensions and Tolerances

This module examines material conditions, geometric characteristics, symbols, and features (Estimated completion time: 1.4 hours).

Assemblies and Fits

This module explores how dimensions and tolerances impact how components assemble and/or fit together (Estimated completion time: 1 hour).

Threads and Fasteners

This module details the size, types, and characteristics of threads and threaded fasteners (Estimated completion time: 1.3 hours).

Geometric Dimensioning and Tolerancing – Part One

Introduction to GD&T

This module covers dimension, tolerance, geometric tolerance, the purpose of an engineering detail drawing, and the history of the Y14.5 standard (Estimated completion time: 0.9 hours).

GD&T Terms and Symbols

This module details the symbols and terms of engineering drawings, as well as the components of a dimension (Estimated completion time: 1.5 hours).

Rules of GD&T

This module details the rules required by ASME Y14.5 for engineering drawings (Estimated completion time: 2 hours).

Geometric Tolerances

This module explains how engineers use geometric tolerances to convey the design intent of the form or location of features when size tolerances may be too restrictive (Estimated completion time: 1.6 hours).

Datums

This module explains how datums are the foundation that provides a method of aligning geometric tolerance zones to ensure features meet their intended design (Estimated completion time: 1.4 hours).

Geometric Dimensioning and Tolerancing – Part Two

Form Tolerances

At the end of this module you will understand what a tolerance zone is, and be able to identify a tolerance zone for straightness, circularity, cylindrical, and flatness geometric tolerance (Estimated completion time: 1 hour).

Profile Tolerances

This module explains how profile geometric tolerances are used to define the limits of contours of lines and surfaces containing straight lines, arcs, partial cylinders, and even mathematically defined curves (Estimated completion time: 0.9 hours).

Orientation Tolerances

This module explains how orientation tolerances control the alignment of features to datum features (Estimated completion time: 1.2 hours).

Runout Tolerances

This module explains how runout tolerances reduce vibration and uneven wear of the features to which the tolerance is applied (Estimated completion time: 0.8 hours).

Location Tolerances

This module explains how geometric tolerances control the position of axes, center planes, surfaces, and midpoints of features to datum features (Estimated completion time: 1.2 hours).
