Here are some examples

    # join GreenlinkPPlan_s1 GreenlinkPPlan_s2 #simple syntax failed as this is complex join, so do as below

    join pwall01@MiddleEarth:6 pwall02@MiddleEarth:1

    join pwall01@MiddleEarth:7 pwall02@MiddleEarth:2

These two use the ‘simple’ syntax

    join GreenlinkKPlan_s1@MiddleEarth GreenlinkRDPlan_s1@MiddleEarth #simple join

    join YK-GimlisInletsPlan-s1@MiddleEarth YN-GimlisInletsPlan-s2@MiddleEarth -count 2  #another simple join

And some more complicated ones

    join pwall01@MiddleEarth:0   kwall02@MiddleEarth:end

    join pwall03@MiddleEarth:end kwall01@MiddleEarth:0 JAwall02@MiddleEarth:5 #three lines joined, and JAwall02 is joined part way along it’s length at node 5
