Well now that flowstone as an area is in Therion we can look at tweaking the metapost code. The ASF's images for flowstone is at: http://www.caves.org.au/m_stab-1c.html#6.0 It differs from gour pools in that the gour symbols all join or touch each other whereas the flowstone symbols are all separate. In the metapost code below I have increased the horizontal and vertical spacing a bit and my wife Jill thinks its pretty close now to the ASF symbol on the web. code metapost beginpattern(pattern_flowstone); pickup PenC; p:=(-.35u,0){dir -60} .. {dir 60}(0.35u,0); draw p; draw p shifted (0.35u,0.4u); # was (0.35u,0.3u) patternxstep(1.0u); # was 0.7 patternystep(0.8u); # was 0.6 endpattern; def a_flowstone_ASF (expr Path) = T:=identity; thclean Path; thfill Path withpattern pattern_flowstone; enddef; endcode Now .... rotation. We draw flowstone and gours oriented to the direction that they are in the cave. I think they are pretty much the only area fills that we orient. The rest like mad, sand, clay, moonmilk etc are all unorientated. Mike Lake
