Choice of lines don't appear in "Lenght of lines" list


I have seen this problem a few times : some lines don’t appear in “Lenght of lines” list in the formula menu. I usually make sure that the line exist by adding it before trying to ad it in the formula.

Any ideas what could cause that?

if you post .val and .vit files and a more detailed description how to reproduce the issue, I would be happy to take a look at it


Time travel, for one thing. That is, looking for a subsequent line’s length when editing a previous object.

For another, if the line is actually part of a different line, or actually made of several lines.

& that’s just the ones I’ve met! Which is why @kmf expressed that the only way to be sure to give a pertinent answer is to see the pertinent file(s).


Thank you for your fast response!

OK, I’ve rechecked and it seems it’s working now. Maybe I’ve made a mistake while trying to add the lines (wrong name of the line, maybe?)…

Anyway, if I see the same issue again, I will let you know.

Best regards,


@Pneumarian was right on with the “time travel” observation. if you search through past posts on this forum, you will see discussion about editing the order (history) of objects. I have sometimes used one pattern file to experiment, then very quickly been able to recreate it with a cleaner approach once I have learned what will work
