[PCB_FORUM] Via at SMD Thru

Hello group,

I have uncovered what I think is a bug in SPECCTRA.

I am trying to route a BGA pin top side to a bottom side SMD component.
I want the thru via to be placed in the SMD pad.  The nets are power and
ground and have been set up as CLASS POWER.

In specctra, in the GUI interface, I see a button under the
PCB/Rules/Wiring/General for "Via at SMD Thru"
The same button does not exist under CLASS/Rules/Wiring/General.
HOWEVER, when I manually type at the command line:  rule class POWER
(via_at_smd on (grid off) (fit off) (thru on))  specctra understands it
and does what I intended it to do.

It seems impossible to accomplish this through the GUI interface.

Can anyone else confirm this?

Thanks,
Chris Nunn
