Hi,
The caliper function does not create accurate results, in general, repeatability is very bad.
I think this can be improved by adding a "mean caliper" functionality.
Currently, there is only min-max caliper functionality which is not working when looking for average caliper measurement.
I use geometry step as a workaround, use Find Edge to locate edges, Distance function and finally Calculator step to calculate the average caliper/distance.
Mean Caliper function could be added to Caliper function for more repeatable results with ease of use.
