I agree that you should put the app back where it belongs…
here’s a ruby script to copy the v15 file into v16 Plugins folder…
copy/paste into the bottom of Ruby Console and hit return, restart SU…
v15_folder = "/Library/Application Support/SketchUp 2015/SketchUp/Plugins/ImaginationVisualizer"
v15_extension = v15_folder + '.rb'
v16_folder = File.expand_path("~") + v15_folder.sub('5', '6')
v16_extension = v16_folder + '.rb'
command = 'ditto ' + v15_folder.inspect + ' ' + v16_folder.inspect + ' && ' + \
'ditto ' + v15_extension.inspect + ' ' + v16_extension.inspect
system(command)
