Adding round/softness to edges

I am trying to create a Rounded/Soft font from a Sans Serif one. Need some ideas on how to go about this properly. See attached font.

Basically, the edges/corners are really sharp.

I don’t think there are any shortcuts. It’s quite a laborious process to round each corner to the desired radius either by adding nodes, or combining contours.

A lot of work can be saved by cut/paste contours from one glyph to another after carefully designing a few.

We should ask for a shortcut!

  1. Select a point.
  2. Push a button.
  3. Make selected point off line.
  4. Add online point slightly ahead and online point slightly behind.

Couldn’t be easier!
