Yes, when the ‘simple’ join syntax fails you need to give each line you 
want to join a unique id (look in the Xtherion window pane on the right hand 
side).  It requires a bit more concentration, but it works well.

‘join’

Description: Join works in two modes: it joins either two scraps or two or more 
points

or lines in a map together.

When joining more than two points or lines <at the same point>, use one join 
command for all of them, not a sequence of join commands for pairs.



When joining scraps, only passage walls are joined. It’s a good idea to place 
a scrap join

in the passage which is as simple as possible, otherwise you have to specify 
join for each

pair of objects which should be joined <this is what you have found Graeme>.



Syntax: join <point1> <point2> ... <pointN> [OPTIONS]

Context: none, scrap, survey

Arguments:

• <pointX> can be an ID of a point or line symbol, optionally followed by a 
line point

mark <id>:<mark> (e.g. podangl_l31 at podangl:mark1). <mark> can be also 
‘end’ (end

of the line) or line point index (where 0 is the first point).

A special case is when <point1> and <point2> are scrap IDs—than the closest 
scrap

ends are joined together.

Options:

• smooth <on/off> indicates whether two lines are to be connected smoothly.

• count <N> (when used with scraps) ◃ Therion will try to join scraps which 
connect in

N locations/passages.
