Therion 0.4.0 automatically creates a scrap containing centreline if no map is selected in the thconfig file. This scrap can easily exceed 1 MB in size in large caves (e.g. 4.5 MB for Dead Bats Cave). You may avoid its creation by selecting any of defined map objects in 'export map' command.
I have selects in my thconfig file: #Map(s) to include in output select toplevelplan@terikan select midlevelplan@terikan select aboveriverplan@terikan select riverlevelplan@terikan
which I assume is what you mean by the above?
yes, if toplevelplan@terikan and others are maps, not surveys
And the underlying data hasn't changed for months so I don't think this is the problem.
right, but therion changed from 0.3.10 to 0.4.0 -- the automatic generation of scrap with all centreline data is a new feature
The one thing that seems to make a differnce is base-scale. If i change it from 1:1000 to 1:2000 then the error changes. Now I get:
...
[329] [330] [331] [332] [333]
l_slope->...;exitif.cas>dlzka+0.3u+(krok/3);endfor ;if(EXPR1)=1:pickup.PenC;d... l.33489 ...2,225.273,33.9682),(3,208.773,33.5305))
It is some issue with the slope symbol definition in small scale maps -- I'll check it. Note that it occurs earlier than the out-of-memory problem (line 33489). Martin
