Now I have added this into my surveys, I see that the centreline is rendered as solid lines when you include the centreline (and have not set the centreline symbol group to be hidden), but if you do not include the centreline then the survey lines renderer in the scraps are just dashes at each station rather than complete lines running the complete distance between pairs of stations. Not a problem, but curious as to why I get two different styles for cave survey lines.
Then I tried this on my 66km system survey and with centrelines set to show in my layout, I found metapost used up all the words of memory it is allowed so I get no output. From my logfile:
Here is how much of MetaPost's memory you used: 6498 strings out of 6522 15689 string characters out of 34452 1500001 words of memory out of 1500000 1389 symbolic tokens out of 16384 12i,75n,41p,489b,3f stack positions out of 300i,84n,5000p,608b,15f 10510 string compactions (moved 140463121 characters, 13446441 strings)371 output files written: data.1 .. data.4017
How can I get around this limitation?
Not sure if this is the right answer but see if the info from line 113 of http://sources.debian.net/src/therion/5.3.16-3/debian/README.Debian/ helps at all You'll have to translate it to windows-speak Wookey -- Principal hats: Linaro, Debian, Wookware, ARM http://wookware.org/
