[Therion] Joining surveys at a curved/sloping pitch

Many thanks for that.

I was afraid you would answer something like that though. Laborious
manual editing it is.

I was wondering if maybe I could manually add the pit line into the
lower scrap's .th2 file using a text editor. Make it invisible, outline
out, then use XTherion to move it into position so that it touches the
lower scrap properly, and then manually join all the linepoints in the
.th file. That way, the shape of the curve should be perfect, with
minimal distortion, and not relying on line thickness to hide the
approximations.

It's a real shame to have to do it like that though. Imagine instead
that I could create a scrap filling only the gap, in the *upper*
survey's .th2 file (fairly easy to do). Then imagine I could say:
fillerscrap at uppersurvey -color lowerscrap at lowersurvey.

(Whether this is done as a lookup, or as a direct command or property
doesn't really matter, just as long as it is possible.)

This would solve the problem without needing all the manual
approximations and attempting to copy vectors between surveys.

Feature request?
