Hi again

Been working on presentation some more, and have two more conundrums.

How do I use a layout to hide altitude points attached to the cave walls? 

How do I show ‘fixed’ station points and show their names, but hide all other station points and names?

debug station-names is too much.

A sample of some of the show/hides I am using…

 #CAVE APPEARANCE

  #---------------  

  symbol-hide point cave-station   

  symbol-show group cave-centreline   #shows passage not yet drawn

  symbol-hide group surface-centreline

  #hide labels

  symbol-hide point label   

  symbol-hide line label

  symbol-hide line arrow 

  symbol-hide point altitude

  #symbol-hide line altitude  #causes error

  symbol-hide point station-name  #specific station name points – this line works fine with show or hide

  #hide sections

  symbol-hide point section  #cross section locations

  symbol-hide line section   #cross section cutting planes

  #blackout passage
