Adding corner component and nothing happens


I am a complete newbie trying to learn the program so sorry if I’m missing something completely obvious. I can’t seem to work out how corner components work. I’ve created a simple workflow to demonstrate what my process is.

  1. I create a new glyph and call it “_corner.leftSerif”
  2. I give the glyph a width of 0, set it on the baseline and set it to 0 on the right side-bearing
  3. I create in a separate glyph a simple square. I select the bottom left point, I right click it and select “Add corner component”.

After all of that nothing happens. Please see screenshots attached

The _corner glyphs needs to contain an open path.

Worked like a charm! Thanks! … I knew I must have been missing smth totally glaring :woman_facepalming:
