lost vias

[tanli]

For current (gtk) CVS version: some vias are lost after
reopening the pcb file. I have not noticed any
regularity except for rather big lost vias size (say,
with radius about 140 mils).

Are you able to give exact instructions on how to reproduce
this or is it too random?

Thanks

Have tried just now:

- start new layout
- add two vias near each other
- maximize vias'es sizes with 's': vias must overlap each other
- 'save as'
- 'load'
- see reported bug

P.S. it is for current cvs gtk version

whats going on is that the code which creates vias (which
gets called when the board is loaded) won't create vias
which overlap. However, you can cause overlapping vias in
an open layout by placing them near and then increasing the
size.

We need to decide if we will allow overlapping vias (making
sure that we don't break the connection scanning code) or if
not we should check when they are resized or moved. My vote
is the former.

Dan,

I see. Can such via creating code (I mean "check when they
are resized or moved") accept overlapping in case vias under
question are connected (are at the same net)?
