A Sketch plugin to draw shapes between two circles based on their inner and outer tangents.
Inspired by the Adobe Illustrator script by Hiroyuki Sato



  1. Select two circles (works just for two for now)
  2. Run one of the Metaball options (Arc, Inner Tangents or Outer Tangents) via the Plugins menu (or use Runner)
  3. Boom! A shape is drawn between the two circles ;)


  • Download the latest release of the plugin
  • Un-zip
  • Double-click on metaball.sketchplugin
