Pcbnew: Enhanced algorithm to calculate board connections:
* A track is seen connected to a pad if the track end is inside the pad shape. * Pads inside pads are now seen connected, if the center of the pad is *inside* the other pad. * this is made to be sure a large copper area is shared by the 2 pads, and to keep algorithm fast.

2011-Dec-19, UPDATE Jean-Pierre Charras <jean-pierre.charras@gipsa-lab.inpg.fr>
|
||||||
|
================================================================================
|
||||||
|
Pcbnew:
|
||||||
|
Enhanced algorithms to calculate board connections:
|
||||||
|
- A track is seen connected to a pad if the track end is inside the pad shape.
|
||||||
|
- Pads inside pads are now seen connected, if the center of the pad is
|
||||||
|
*inside* the other pad.
|
||||||
|
(this is made to be sure a large copper area is shared by the 2 pads,
|
||||||
|
and to keep algorithm fast).
|
||||||
|
Algorithm to calculate pads connections is still very fast.
|
||||||
|
However some other functions (drag pads, track len calculation ...)
|
||||||
|
still need the track end exactly on the pad position.
