The purpose of this VI is to store the results of the VIs that returns points and angles in a Results Manager (Database of results produced by each step), so that they can be easily accessed by subsequent steps like coordinate system or caliper. You should not need to use this VI to access the data produced by the Find Circular Edge. Just use the outputs of IMAQ Find Circular Edge 3 VI.
But that's a good point. In this case, since your script does not use either step after the Find Circular Edge, we should not have dropped this VI to make the code simpler.
We chose to use a producer/accessor model instead of dataflow, because all the VIs that output points and angle are heterogenous. Some indicators are a clusters of points, some are arrays or points, some are array of cluster of points and other stuff etc. Using dataflow would have required to generate specific code for each producer.
Hope that makes sense.
