Ignoring other errors ...

If you wish to make unqualified method calls, from within the module, then the methods must be defined within an anonymous proxy class block.

This also allows you to make qualified method calls from outside the module, like:
Visual::Plugin_A.field_build()

require("visual_visual_mod.rb")
require("sketchup.rb")

module Visual;;Plugin_A

  ### CONSTANTS
  #


  ### MODULE VARS
  #
