24/2/2023: Trying it now (v.9.6.3) - data in from many formats; auto declination; Survex style rotate; import sketches; drawing tools, scaleable symbols, many undo levels; exports into svg (for Inkscape tweaking?) and pdf (for 10€). Will take in a number of caves for an area view / drawn survey(?) but whether it will cope with hundreds of surveys around Matienzo is another matter. Looks excellent for a stand-alone survey, at least!
