Checking of Therion "environment"

You may check Therion’s system variables easy - write into Command line options field in Compiler window “- -print-environment” and press Compile.

The result should look as:

therion 0.3.7
configuration file: perlovy.thconfig
reading ... done
INIT=/Caves/therion/lib
SOURCE=/Users/martin/.therion:/usr/share/therion:/usr/local/share/therion
METAPOST=mpost
PDFTEX=pdfetex
 

The INIT path is a place where Therion looks for therion.ini and xtherion.ini. Example is from MacOS X.

Editing text files in "Text Edit" window (F1)

Creating and editing objects in "Map Editor" window (F2)

* The name of edited .th2 file and name of active scrap you may find in top border of window.
* Allways check the "object setup area" on right side and "status line" on bottom of it. You may find there any necesarry information with help to create object with correct parameters and in correct place. 
* If you press the "Escape" key you leave the "Insert Mode" and switch to "Select mode". The "Select mode" works in two steps - **select** - after first click you may check the parameters of object in "Status line" or "File commands" or "object setup area" and - **move** - after second click you may move with object.
* If you add line object, you may start to insert new line simple by pressing of Ctrl+L keys, you don't need to escape from "Inserting mode" first. 
* Allways check the small yellow tick on first point of line object. It shows the FREE space side of line. It means you should draw walls in counterclockwise dirrection, the blocks in clockwise dirrection, pit or chimney in counterclockwise dirrection, etc. If you did mistake - there is "reverse" option in "Line commands" section.

Changing the subtype of line

A wall does not need to be divided into small parts according to subtype. You can use one line of type wall and assign the appropriate subtypes to line points from beginning of line (where the small yellow tick is). The subtype bedrock will return the line wall back to default (solid rock) type.

The symbol may have an attribute subtype. The subtype is very common for line symbol wall. You may use these subtype for the wall: invisible, bedrock (default), sand, clay, pebbles, debris, blocks, ice, underlying, unsurveyed, presumed.

You change the subtype of the point in on the wall in the small black window in Line point control part of control panel. Simple write there subtype xxxx (no dash). This changes the subtype of the wall from that point on, until the end of the line or the subtype of another point is changed.

Imagine you have part of the wall pressumed - there is a wide crawling and you are not able to recognize one of the walls. At first point of missing wall you assign subtype presumed and at the end of missing wall you assign to the point of wall line the subtype bedrock.

You may assign only one subtype for one line point.
