Measuring

Chapter 6:

Measuring

Measurements can be performed manually or automatically (CNC option) using crosshairs or optional

optical edge detection. Measurements can be limited to probing feature points, or can include the con-

struction or creation of new features in addition to probing. However measurements are conducted, the

fundamental measurement process and the tools required to perform measurements remain unchanged.

Here’s what you’ll find in this chapter:
