Class Method Details

.open_drawing(drawing, **options) { ... } ⇒ void

This method returns an undefined value.

Calls #run to get an app instance then call open drawing with that app (see #open_drawing)

    app.open_drawing(drawing, **options, &block)
  end
end

.run(options = {}) {|App| ... } ⇒ void

This method returns an undefined value.

Initialize an instance of app with the options

source

App.run do |app|

drawing = app.open_drawing('test.dgn')
drawing.scan_all_text do |model,text|
puts "#{model} #{text}"
end

end

Options Hash (options):

  • :visible (Boolean) —

    Is the app visible

Yields:

  • (App) —

    the_app yields the instanciated app
