How come when I do this, smooth/corner points info is all lost and turned into corner points
In my work I am often supplied with .UFO
files made in RF and when opened in Glyphs they similarly only have corner points.
Select all glyphs and Tidy up Paths.
The blue/green distinction is just an extra help inside the editor, and IIRC Robofont and Glyphs handle these slightly differently. In any event, PostScript does not differentiate between the two states.
I just tried this and the smooth state was saved and read to/from .ufo correctly. Can you send me a .ufo that shows the problem?
I cna’t hit tidy up paths because it will break the compatibility. I will send an example to you shortly Georg.
