[Therion] Inconsistent SELECT behaviour for pdf and xvi map output with background sketches..

[Duncan Collis]

Hi, Martin.

Thanks for the clarification. That leads me to a final question: is it
possible to select a particular survey and also get morphed sketches
in the output XVI file? I've tried to do this without success, but
maybe there's something I am missing?

I've tried:

select survey_1 at system
select survey_2 at system

and get an XVI file with centreline for survey_1 and survey_2 and no sketches.

If I try:

select map_A at system
select survey_1 at system
select survey_2 at system

I still only get the centreline. Is this expected behaviour?

Best regards,
Duncan.
