[Therion] Hiding cross-section symbols

27 Nov 2021

      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!
