i'm kind of confused: looking at the UIS official symbols ... ceiling meander is shown with ticks outside, therion ceiling-meander draws with ticks pointing inside. also chinmey line in UIS is dashed with ticks. in therion is just dashed. (therion ceiling-step line is dashed with ticks). marco

It is "error" in UIS symbols. Tick means "free air" - as step or pit. You should not use ticks one time for "rock", second time for "air".

You may use any symbol from any symbol set for your particular map. m.

That is news to me that the UIS have published these symbols with this error in for years? I always took the published UIS symbols to be the definitive reference, and inferred from them that the ticks indicated the direction that the floor was lower (for floor height changes) and the tick indicated the direction that the ceiling was lower (for roof height changes). So have I drawn all my aven lines wrong for the past 5 years? Footleg On 13 June 2011 09:19, Martin Sluka <martinsluka@mac.com> wrote:

This is more drawing maps philosophy problem. It is absolutely up to you and your caving group which symbol set you will use. In therion symbol sets you may find both (I hope). Martin

In fact both problematic symbols are defined in SKBB (our local caving group) symbol set. Unfortunately, UIS set is incomplete in therion and missing symbols are taken fom other symbol sets even if you select UIS set in thconfig, as it is in this case. We can add those two symbols in the next snapshot, other symbols upon request. You can display an overview of currently defined symbols for all symbol sets by running therion --print-symbols which creates symbols.xhtml file (you can display it in Firefox). Martin
