Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.

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.

Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

In this learning activity you'll examine how a sine bar is used to measure angles.

Students take a 13-question quiz to practice reading 25- and 50-division Vernier height gages.

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

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

In this video, you’ll explore how to calculate, setup, and cut a taper using the tailstock offset method.

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.

In this learning activity you'll practice reading a micrometer.

Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.

Introduction to selecting the proper punch and die for air bending or bottoming when forming on a press brake. Includes charts and methods for selection.

Learners will test their ability to read a depth micrometer in this interactive quiz.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.

In this video, you’ll explore the engine lathe, its basic components, and you’ll learn to operate its machine controls.

Learners examine pictorial drawings used in engineering including sectioned and exploded drawings. A sketching quiz is provided to help the learner create simple pictorial sketches by using orthographic views and an isometric template.

The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes.

Learners examine the use of the tolerances displayed in a title block by calculating the minimum and maximum allowable size of a fabricated part. In a brief quiz, students determine whether a part is usable or should be scrapped.

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.
