In Gocator, regions of interest (ROI) have always been able to track the horizontal or vertical movement of a part using X, Y or Z anchoring. Now, regions can also track the angular movement​ of a part using angle anchoring. This means that your ROIs can now track part rotation and achieve higher repeatability as a result.
