You have a good point, there are times when the same point should appear in both plan elevation and data, these ideally should be single entry.
I do not have a solution but a few thoughts. Page 20 of the book gives an example of adding a continuation to a station and giving and attr. I think this is in Centreline data. Which leads to Can a continuation point on a plan of elevation use the information in the Centreline continuation. If so this sorts your problem. If not an an attr could be used to add a code to link all three continuations, not ideal but probably makes the filtering easier. Not tested any of these things as away and only have phon Andrew -- Sent with K-9 Mail On 24 August 2022 21:10:56 BST, A Gott <alastairg...@gmail.com> wrote: >HI Therion friends, > >A friend posed an interesting question on a data set we hold in Therion.
