There is a Pas Size Round-off in the Preferences or the "Terminal > Settings" tab.
Change the Pad Size Round-off to 0.05 or whatever you want. |

Hi Tom.
What is to be considered the starting point for the toe? Lead length? Or landing pad length? Nominal, max? I haven't been able to locate any documentation that indicates where this starting point is. I don't have a copy of the IPC-J-STD-001 yet. Hope to have that soon.

IPC-J-STD-001 clearly states that the Toe solder joint goal should be a minimum of 25% of the Terminal Height or 0.50 mm, whichever is greater.
Look in the Tables. |

I do want to change the pad round off to be 0.05. Where would I do that globally? For all packages?

Preferences > Terminals > Corner Concave > Settings > Pad Size Roundoff
As soon as you select another Terminal like "Cylindrical End Cap" you will get a notification: Apply Setting Changes to all surface mount terminals? Yes or No |

Don't forget to change Through-hole too.
Preferences > Terminals > Through-hole > Pad Size Round-off.  |

I don't see a solder joint goals download anymore. Is the methodology obsolete?
