get metal layer associated with via

Hi,

Is there any way to get the metal layer associated with via
independent of technology.

for example if via name is DFM_M2_M1 I should get the metal layer
associated with this via ie. M1 and M2.

Hi,
Uh, is this even possible?
As far as I know all vias are defined by their technology, thus we can
have a via named "Confusing_Owntech_v4" associated with layer metal1 &
metal2 (the person who does something like this to define a 2x2 via
array this should be dangled upside-down in a volcano).

If you dump a technology, there would be the definition of vias in the
generated ASCII techfile, with their corresponding properties (layers,
dimensions), so there is a way to access these associated layers.
Some technology name vias as "via3" or "via34" etc. so I don't think
it's a good idea to define layers by just their name.

Maybe leGetContactRule() does what you want? Check the manual.
