the "add beam element" page in the manual says that to add a beam one of the command is:
structure("drawbeam","beamid",id,"edgetags",t1,t2,...,tn)
but adding a beam with adonis, in the command panel history, i read:
structure("drawbeam","beamid",1,"id",1,"attachto","boundary")
so, where manual says to use "edgetags", program uses "id".
command lines in the manual also miss the "attachto",<keyword> part of the command.
i'va attached in this post my proposal for the html page of the manual.
