Useful Regular Expressions

• Select shell (FLOOR) named "Level_8" and all spaces following, up to "Level_9"
  
  (?s)(^"Level_8.*)(?=^"Level_9)
  
  Note that (?s) enables multi-line matching, and (?= begins a non-capturing group
  
• Match all EL1 walls and reformat with space vertex identifier
  
  (?s)(^"EL1\s)(\w{1,20}\s)(Wall\s.{1,5}\..{1,9}\.)(.{1,9})(\)"\s{1,20}\=\s)(\w)(.{5,100}SPACE\-)(V\d{1,2})
  
  Replacement String: \1\6\3\8\5\6\7\8
  
• Strip least-significant identifier from Roof / Flr components:
  
  (^"EL\d\sRoof\s\(.{1,9}\..{1,9})(\..{1,9}\)")
  (^"EL\d\sFlr\s\(.{1,9}\..{1,9})(\..{1,9}\)")
  
  Replacement String: \1)"
