Hi everyone. Somebody could explain me how calypso calculate the diameter with two points diameter function? And which is the difference between the results of two point diameter and min circumscribed diameter?
Thanks a lot for the explanations

Two point diameter should be based on two opposite points. Here you can use (E) envelope.
Min circumscribed diameter is based on 3 points.

Taken from manual so you can take a look - there are pictures.

2 Point Diameter characteristic
  • (LP) Two point distance dimension
    The circle is fitted into a Gaussian element (LSQ feature). For each
    point of each scanning path, the symmetrical point is determined.
    The smallest and largest two point distance is determined from all
    two point distances. The corresponding points are assigned to them.
