Explanation of the Quick Measure Features Most Often Used (Continued)

Diameter of a Shaft

- The first screen will tell you to measure the plane. (Explained above)
- The diameter of the shaft works just like the diameter of a circle.
- The second screen tells you to measure the circle. (3 points minimum)

- After you press the Yellow button the measurement will appear on the screen.

Distance between two surfaces or planes

- This feature is used to measure thickness.

Thickness of the block
Depth of a pocket
Height of a block
- The first screen will tell you to measure the plane.  (Explained above)
- The second screen will tell you the same thing as the first screen.  (measure the plane)
- After you complete measuring both planes and press the Yellow button the measurement will appear on the screen.

Distance between two holes or circles

- Distance between 2 holes can be used for internal and external (bosses) holes.
- Steps for finding the distance between 2 circles.

1. Top plane
2. 3 points on first circle (same as finding a hole diameter feature)
3. Top plane
4. 3 points on second circle (same as finding a hole diameter feature)

- When all the points have been taken the screen will give you the measurement between the holes.

Angle between two surfaces

- To find an angle you take points on 2 planes.
- Instead of taken the top surface, you start on the one of the angled surfaces. As shown on the picture below.

When all the points have been taken the screen will give you the angle on the part.
