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

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 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.

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.
