Link style with curved and angled label

Hi guys , I would like to share one of my link config.

LINK 6-21
        TARGET ./
        NODES 6 21
        BWSTYLE Angled
        VIASTYLE curved

For some reason , last directives (bwstyle and viastyle) are not working for me.
Still reading documentation and trying figure out, any idea would be wellcome.

BWSTYLE angled requires a truetype font, so you need to use FONTDEFINE to define one, and then BWFONT inside the link to use it. You should be getting warnings in the log file for this.

VIASTYLE curved - how do you know it isn’t working if you didn’t define any VIA points?

Thanks , after add VIA x y points it is working,
