"-context line section" did the trick. Once again - Thank you! It seems odd ... The first question I had was solved by adding an 's'. This time it was solved by removing an 's'. The function described on page 27 of the Therion book seems to be related to a line of type section. I use those all the time. That kind of line indicates where in the cave the cross section goes. I then add a point of type cross-section which places the scrap on the map. An option for the point tells which scrap goes with it. The thing about this map is that it has a LOT of cross sections crowded into a small area. Placing a scrap near its section line is not always possible, so I use an arrow line to indicate which scrap belongs to which line. Doing a symbol-hide on the sections takes out both the scraps and the section lines, but leaves the arrows. The map is much less busy, but those arrows are just hanging out there with no obvious purpose. Now I know how to take them out too. ======== Bill Gee On Saturday, November 27, 2021 1:31:34 PM CST Andrew Atkinson wrote:

Or

Annoyingly on xtherion one of these is called something like cross section, I cannot check as I'm on a phone.
Have you tried the built in function for showing cross sections? It gets a bit of getting use to but works well. Page 27 of thboolk.
You might be able to use, but I've never tried.
-context group sections
Be warned context doesn't always work, I imagine as they are very untested by end users, but a bug report has ended up with a rapid fix in the past 👍 One of the first two definatly work as I've used it on labels for cross section, well it worked for labels.

And a followup question! More secret incantations ...
Although the cross-section lines and scraps are now gone, the arrows that I used to connect them are still there. I tried adding an option to the arrow line, like this:
-context sections
but that only produces an error "not enough option arguments -- -context -- must be 2". I changed it to read
-context line sections
and got "invalid object context -- line sections".
Page 29 of the Therion Book implies that something like this should be possible. I don't want to hide ALL arrows - just the ones that are used in association with cross-sections.
Maybe I need to use some other context besides "sections"? Perhaps define those arrows as context of "section_arrow", then use "symbol-hide group section_arrow"?

Yep, that did it. Thanks!
Now that I know what to look for, I see on page 52 of the Therion Book that "sections" is listed as a possible group under symbol-assign. It is not in either symbol-hide or symbol-show, which is why I missed it.

All you needed was an s :)

In a map layout, what is the symbol-hide command to not produce cross-sections? I have tried these without success:
layout NoCrossSections symbol-hide point section symbol-hide line cross-section symbol-hide section section symbol-hide section cross-section symbol-hide group section symbol-hide group cross-section endlayout
For all of these Therion says "Unknown symbol specification".
Thanks! ======== Bill Gee
