> # Change the legend callout for stalagmaflats > text en_US "point u:stalagmaflat.AMER" "stalagmaflat" I don't think your command should not include the symbole set name “AMER” as that isn’t included in the legend. It should be text en_US "point u:stalagmaflat" “sttlagmaflat" Dave Clucas

How to use user-defined symbols
by Bill Gee 09 Feb '14

09 Feb '14

Hello everyone - I have been struggling for the last several days trying to figure out how to build and use my own symbols. I need a symbol for two kinds of formations - Stalactiflats and Stalagmaflats. These are basically stalagmites which are fat (several feet diameter) and flat on top like a table (or flat on the bottom). It appears there are two problems to solve. The first, which I address in this question, is how to get xTherion to use a custom symbol. The second is to figure out how to draw the symbol in Metapost. For now I am ignoring the second problem. One step at a time! After spending several hours going through Therion By Example, I was able to get a custom symbol to work, but only by replacing an existing symbol. I used the NSS "gradient point" example. Changing the Metapost code as shown does not produce any error messages. However, it also does not produce a symbol in the PDF output. All I get is a red dot. =============== code metapost def p_stalagmaflat_AMER (expr pos,theta,sc,al) = U:=(.15u, .4u); T:=identity aligned al rotated theta scaled sc shifted pos; pickup PenC; #Left Hand side thdraw (-.3u, -.2u) -- (-.7u, .1u); thdraw (-.2u, -.1u) -- (-.4u, .6u); #Centerline thdraw (0u, 0u) -- (0u, .9u); #Right side thdraw (.3u, -.2u) -- (.7u, .1u); thdraw (.2u, -.1u) -- (.4u, .6u); enddef; initsymbol ("p_stalagmaflat_AMER"); endcode ================== Since I am not replacing an existing symbol, I leave out the "symbol-assign" line. In xTherion I try to use this by inserting a point of type "u" and adding an option "-subtype stalagmaflat". I think this is where I am missing something ... How to call the custom symbol with a "u" point. Is this the right syntax? In the worst case I suppose I could set it up to replace a symbol that I won't use for this cave - a ladder, for example. That would probably cause quite a bit of confusion down the road, so I would much prefer to avoid it. I am using Therion 5.3.13 on 64-bit Fedora 20. Thanks - Bill Gee

I looked at some (not all) of the samples and did not see anything obvious. Thanks - Bill Gee Hi Bill Yes that's an elevantion. Whether it is extended or projected depends on how you set it up in the first place. Are you importing paperless data from pocket topo, in which case I suggest you use Andrew Atkinson's Topparser to import your data and set you files up properly. We use a single thconfig file which generates the elevation pdf and then imports it (as a pdf) into the image being generated for the plan (or vice versa, either can work). I suggest that you look at the Cheddar catchment stuff at http://www.cave-registry.org.uk/svn/CheddarCatchment/ particularly the file http://www.cave-registry.org.uk/svn/CheddarCatchment/thconfigres+whitespot or for a slightly simpler alternative, the file http://www.cave-registry.org.uk/svn/CheddarCatchment/Spider/thconfig Graham

Problems with Execution
by Markus Boldt 08 Feb '14

Suddenly I have a Problem with getting drawings from Pockettopo to Therion. If I have made a Therion-Export-File on my PDA and I want to load it in Therion-Map-Editor I get the Error like below. If I say OK the XVI-File will produced anyway! Then I have tried to import that File to the Editor and I get the error below. I have done this procedure very often. But now it is a new Computer. OS is Windows 7 professionell, therion is 5.3.13 Has anyone an idea? Markus

Have a look at this. http://therion.speleo.sk/wiki/doku.php/metapost You will find a symbol which I defined for a stalagmite boss which I guess is what you are talking about. def p_u_boss (expr pos,theta,sc,al)= T:=identity aligned al rotated theta scaled sc shifted pos; pickup PenD; p := (0.08u,0.25u)..(0,0.29u)..(-0.08u,0.25u); q := (0.16u,0.5u)..(0u,0.58u)..(-0.16u,0.5u); for i=0 upto 9: thdraw p rotated 36i; thdraw q rotated 36i; endfor p := fullcircle scaled 0.15u; thdraw p; enddef; To use a user defined symbol click on type U in the points drop down and then after the U, type in a colon followed by the name of your symbol so, in the case of the above "U:boss" Dave Clucas daveclucas.com mycaves.org. daveclucas(a)icloud.com
