This document gives the procedures for layout on the surface of material.

In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.

Datum precedence is a fundamental principle in the design and manufacture of mechanical parts and assemblies.

It refers to the order of importance assigned to different datums, which are specific points, lines, or planes on a part, which are used as references for measurement and geometric tolerances.

2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a holder. A short quiz to test your ability to correctly read this information follows.

2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a three-step block. A short quiz to test your ability to correctly read this information follows.

2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a slotted block. A short quiz to test your ability to correctly read this information follows.

2D and 3D views used to help convey information from a drafter or designer to the welder are provided. This activity will focus on a mounting wedge. A short quiz to test your ability to correctly read this information follows.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.

This learning object is designed to show students they types of information that can be imaged from the Electronic Control Module employed by heavy truck engines.

This Learning Object is designed to identify the various components of a vehicle's seatbelt system, and to show evidence of seatbelt use following a collision.

Learners distinguish between competencies that are effective and robust, and those that are ineffective and weak. The learning object is designed for faculty who are writing or revising courses. It contains audio.

This learning object is designed to assist students in understanding and interpreting collision evidence found in automotive lamps. In particular, the concepts of Hot Shock, Cold Shock, Hot Break, and Cold Break will be visually addressed.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

Explore how aligning on-screen text and narration with graphics can help improve knowledge retention and learner engagement.

This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.

In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.

The learner will understand how to view an object for interpretation in the standard orthographic format and then accurately sketch three orthographic views using 3rd angle projection.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.

In this learning activity, you'll be introduced to Third Normal Form and you'll design a table following these rules.
