In this learning activity you'll explore family structure then enter terms in a grid identifying if that family structure is determined by females, males, or both.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

Learners practice reading prints of a hub. They identify information located on the print and calculate missing dimensions.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

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

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

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 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.

In this interactive object, learners set up a shear, enter the back gauge dimension, and prepare to shear metal in a simulation of the Adira Hydraulic Shear.

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 animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

The learner will measure and record dimensions using a metric micrometer to an accuracy of plus or minus .01 of a millimeter.

In this animated print reading exercise, the learner calculates missing dimensions and identifies surfaces on projected views.

In this animated object, learners read the dimensions of the different types of vehicles typically considered in highway design.

The learner examines the four different ways that a caliber can be used to measure dimensions and distances.
