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 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 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 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.
In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.
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.
