In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
Brain Exercise: Visualization #1
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.
Basic Symbols Used in Engineering Drawings
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.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
Basic Types of Lines Used in Engineering Drawings

GD&T: Geometric Characteristic Symbols
In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.
Gear Nomenclature (Screencast)
In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.
Calculating Horsepower, RPM, and Torque
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Brain Exercise: Visualization #3
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.
Brain Exercise: Visualization #2
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.
Gear Ratio Concepts (Screencast)
In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
Excel: Rectangular to Polar Conversion for Magnitude
By Patrick Hoppe
Learners read how to convert complex numbers to their polar equivalent in Excel.
Digital Terrain Model: Extrapolation of Elevations
Students read how to determine the elevation of an alignment or cross section where it crosses the TIN.
Title Block Tolerances
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.
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.
Excel: Locking Cell References
Students read how to lock a cell that is being referenced in a formula so that it does not automatically show an increment when the formula is copied.
Excel: Rectangular to Polar Conversion for the Phase Angle in Radians
The conversion from rectangular to polar mode phase angle in radians is demonstrated in Excel.
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.
