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.

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

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

The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.

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.

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.

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.

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

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 holder in this interactive exercise that features animated pictorial views.

The learner sorts a variety of foods based on personal preferences. Those personal choices are then classified by food group. The learner views the charts and reads information about the major food groups.

The learner views the operation of a transistor switching from saturation to cutoff. A brief quiz completes the activity.

The student views step-by-step instructions for programming a "job" with the PCII on the Marvel vertical band saw.

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.

Learners read a general description of the function and structure of leaves and examine drawings and microscopic views. A matching exercise completes the learning object.

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