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

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

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

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.

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.

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.

Learners test their ability to visualize a three-step block in this interactive exercise that features animated pictorial views.

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 read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

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

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

Learners test their ability to visualize an angled mount in this interactive exercise that features animated pictorial views.

In this interactive object, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information. A brief quiz completes the activity.

Learners test their ability to visualize a holder in this interactive exercise that features animated pictorial views.

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 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.

In this learning activity you'll illustrate your ability to visualize a slotted block.

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