There are circumstances where it’s desirable to be able to find all occurrences of a given geometrical measurement (e.g. bond distances) through pattern search. They key to achieve this is to highlight the target measurement in the pattern document prior to pattern search. Detailed procedure follows:

1.Create a pattern document of the target molecule/fragment.

2.Make the measurement intended (angle in the example bellow) in the pattern document.

3.Be sure to highlight the measurement (the angle monitor in this case).
4.Perform pattern search (Menu Edit | Find Patterns) in the main document.
