I haven't seen any Sketch plugin that deletes all guides used in the document. So here it is. The idea of that plugin was born in the #sketch channel of Creative Russia community.

The default command bind to remove all guides on all pages and artboards is:

• Control + Shift + Option + R

Open Sketch, on menu Plugin > Reveal Plugins Folder. Download the repo as ZIP and extract to above directory.

$ cd ~/Library/Application Support/com.bohemiancoding.sketch3/Plugins

$ git clone https://github.com/bbsody/sketch-guides-remover
