Is there a way to get the max and min Y coordinates of a polygon so we can just subtract them to get the Y-axis height (in microns for us).
Here's a picture. We called the layer_andnot function to get just the tip as show here:
the following two derivation expressions will give you the min and max y coordinates respectively: (ycoordinate (leftlower_point (box p))) and (ycoordinate (rightupper_point (box p))), where p is the polygon. However, if the actual measure sought is not strictly in the y direction, but rather "orthogonal to the edge" or "towards the outside", then it might be better to find a measure which is independant of orientation. For instance, if you have the edge that delineates the discussed polygon (in read above), you could find a vector perpendicular to it (using rotate), then find the size of the polygon or its box along this vector. Another alternative is to rotate the polygon itself (rotate_polygon) to line up with e.g. the y axis, where the angle is decided by the orientation of the edge, then find its extent in e.g. the y direction.
