thanks again; these were the things I needed to overcome to get it work! 
Now I am happily tracing mine walls (cave walls) over the centerline 
background pictures, and starting to put symbols in.

according to http://therion.speleo.sk/wiki/doku.php/exportselectionformat 
this happens as centreline (polygon draws) and map drawings are 
fundamentally different, if I understand this correctly; is it possible 
there is no way to export them 'layered', I mean the map-scraps 
translucent over the centerline? I would like in some circumstances to 
have it printed within the resulting mine plan, but, if not possible, I 
can live without.

Another question: I am putting line points over the background image 
centerline 'wings' (l+r). Is there, perhaps, a function I do not know of 
which sets the line-points automatically over the centerline left- and 
right-wings?
