 One of Therion's key features is that drawings are created in small pieces - scraps. A scrap is the smallest indivisible part of the drawing that can exported to create an output.\\ One of Therion's key features is that drawings are created in small pieces - scraps. A scrap is the smallest indivisible part of the drawing that can exported to create an output.\\
 Most maps contain many scraps, and if they don't happen to appear perfectly joined by coincidence, then you should "join" these individual scraps to get Therion to morph them together. There are three ways to do it; fully automatically in *.th2 file, semi-automatically scrap by scrap, and manually line by line (if you must specify exactly which lines and points join). The last two are described in Thbook; Most maps contain many scraps, and if they don't happen to appear perfectly joined by coincidence, then you should "join" these individual scraps to get Therion to morph them together.

 +Join commands are put directly into the survey section, not inside any scrap or map definitions - lines are joined independently, ignoring whatever scraps and maps they are defined or included in.

 +Note that this works using passages defined by lines of "wall" type (even if their "-outline" is set to "none"). It does not join other types of line. It normally expects to find pairs of lines, one on each side of the passage. If there are multiple passages that need to be joined between pairs of scraps, you can normally use the "-count" option to say how many possible passage joins Therion should search for.

 You may use join command to join line to line or line to point. So if the beginning of a particular passage is between two blocks you may join walls of passage to points of rock-borders. After the morphing the beginning of passage will be still connected to blocks. You may use join command to join line to line or line to point.

 +The lines (just like maps, scraps, points and stations) are referenced by their ID directly inside their survey - inside a subsurvey, this would be as id@subsurvey (or id@subsurvey.subsurvey for nested subsurveys) - so make sure you have assigned an ID to each line that needs to be joined using the join command.
