Tolerance Zone Coloring
The Tolerance Zone Coloring dialog allows you to change the specified limits and coloring for three tolerance zones.
These zones allow you to characterize errors with three coloring zones. This is often useful for users who have a 1, 2, and 3-sigma toler- ance. Each zone is bounded by limits. The first coloring zone starts at greater than Limit 1 and ends at Limit 2. The second zone starts at greater than Limit 2 and ends at Limit 3. The last zone starts at greater than Limit 3.
In the figure at left, points with errors >0.005” and <=0.01” are colored yellow; points with errors >0.01” and <=0.015” are colored blue, and points with errors >0.015” are colored red. For users who only need one coloring zone, simply pay attention to the red zone and ignore the other two, or set all three zones to the same value.
The tolerance specified in the main Geometry Fit Interface is applied as the Limit 3 value.
The Quick-Set Limits section allows you to set a tolerance for Limit 1 or Limit 3, and then set the remaining limit values based on 1, 2, and 3-sigma values. Click Restore Defaults to return the values to their default limits.
