Glowing lines via nodes How do I add glowing lines on a cube or anything that have vertices on Blender 2.8? I'm a beginner so I thought adding material should work. There is another thread where it explains that but I cannot make only the vertices glow. Also it would be great if I could make the lines a bit thicker. I'm trying to make a on/off button which has glowing lines around. 

Thanks!
You can use Pointiness from the Input Geometry Node
But as you can see here from these wire-frames the geometry plays a big part.



Using a Mix Shader with a BSDF Shader and an Emission Shader and controlling the effect with a Color Ramp
  

Of course, you could remove all the extra geometry that does not affect the effect.
