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.
The metapost code of line symbol for this (line with black dots at rigging points) is already prepared I think. All that needs to be done is to add "line rope" symbol main code. We will try to implement it ASAP. Regards, S. Quoting Hilary Greaves <hilary.greaves@merton.ox.ac.uk>:

Excellent, but don't forget some mechanism for 'spike' and 'thread' as well as 'bolt', and deviations. Obviously blob+line is a lot better than nothing but to a useful rigging guide needs the above details too IMHO. And then there is traverse lines. Will the existing code do a catenary hang between points? And for an implmentation that would actually work in practice some mechanism to have the rope not hang 'through' rocks and floors is needed - that could be trickier...

But if I understand correctly, the rope would be a line, so you would have to - and be able to - specify it the usual way with control points and curves... The tricky point is for portions where you wish to constraint it to be a vertical segment, unaffected by distorsions of the scrap. Eric. Wookey wrote:

Hi Eric, check the samples - Rabbit cave - you may lock the verticality or horizontality of segment of line: line border -id l153-922-620 933.5 607.0 adjust horizontal 932.5 949.5 endline Thbook p. 24 adjust <horizontal/vertical> . shifts the line point to be aligned horizontally/vertically with the previous point (or next point if there is no previous point). The result is horizontal/vertical line segment). If all line points have this option, they are aligned to the average y or x coordinate, respectively. This option is not allowed in the plan projection. m.
