Probing and measuring features
Part features are measured by creating a part datum, and then by probing and collecting points that define
the feature’s shape and location. Feature points can be probed using Measure Magic or by using a specific
measurement function such as the line or circle function.
Measure Magic
Measure Magic analyzes feature data collected by part probing and automatically determines the feature
type. Measure Magic supports the following feature types in the QC5200:
• Points
• Lines
• Circles
• Arcs
When Measure Magic is used, and more than the minimum number of points required to classify a feature
are acquired, the feature type can be changed manually by the user if necessary. However, when a specific
measure function is used to probe feature data, the feature type cannot be changed.
Probing features
The feature probing process is essentially the same for all feature types, and is shown below:
The measurement function is
selected from the
Measure menu or toolbar
Points are probed using the
appropriate video probe
Probing is terminated and the
results are shown by clicking OK.
