Well, I gathered my layout definitions in a single file to avoid repeating and duplicating everything in my 50 thconfig files. This allows me to modify only one layout file to modify consistently all the layouts of all caves. I think heritage + redefinition is a more structured way than commenting out when needed. In fact, I was wondering why user symbols need to be treated differently than predefined symbols in layouts: is that a logical or a technical reason?

You may try copy definitions from a layout file to your layout in thconfig.

comment should do the work.

Talking about user symbols: is there a way to hide them in a thconfig file?

So far, my experience is that symbol-hide is not working for these symbols, the only way I found to hide them is to redefine them to nothing:

layout Preview_layout
 copy LayoutTopoXav
 # ... Hiding lots of symbols

 # symbol-hide line u:fracture
# Does not work: unknown symbol specification -- line u:fracture

 code metapost
     def l_u_fracture (expr P) = enddef;
 endcode
endlayout

There are definitions of two new symbols in MetaPost section of wiki: strata and fault.

Because of all user defined symbols could not use automatic -clip off you should to add this option.

With new version of Therion they should behave as section symbol - without -clip off.
