[Therion] Drawing rigging

[Hilary Greaves]

Hi folks,

I am trying to draw rigging on my elevation in the usual way, i.e. black 
dots for bolts and lines down pitches to indicate where the rope hangs.

In Therion, "rope" seems (oddly?) to be a point symbol (allowing the user 
to place a small pretty picture of a backed up belay anywhere on the 
survey he chooses), rather than a line; further, there doesn't seem to be 
any existing line symbol that will naturally do the trick. (Also, there 
doesn't seem to be any natural way of user-defining a suitable line 
symbol, since lines are oriented and ropes shouldn't be.)

Is there a standard way of doing this?

Thanks for any tips!
Hilary.
