**Work Points, Work Axes, and Work Planes**

Introduction to Engineering Design TM Unit 2 – Lesson 2.3 – Advanced Modeling Skills Work Points A work point is an independent entity whose location is defined in space. Work points may be placed or projected onto part faces, linear edges, or onto an arc or circle. Work points can be constrained to the center points of arcs, circles, and ellipses. Demonstrate how to use a work point in the modeling software. Project Lead The Way, Inc. Copyright 2007

**Work Points, Work Axes, and Work Planes**

Introduction to Engineering Design TM Unit 2 – Lesson 2.3 – Advanced Modeling Skills Work Axes A work axis is a line that extends forever in two directions. Work axes are useful for locating the center of a hole or cylinder, are used in the creation of revolved features, and may be constrained to in assembly models. Demonstrate how to use a work point in the modeling software. Project Lead The Way, Inc. Copyright 2007
