adding/ deleting elements to schematics

[Partha]

Folks,

I would like to know if there are simple fuctions that would do the
following, rather than re-inventing the wheel.

given a net name in the schematic i would like to delete that net &
add a elemnet( say a resistor) between the trminals of the net.

Do i need to do the following,
1. get the net & terminals
2. Delet the net( schDelete?)
3. check and see if the net is vertical or horizontal( by coparing the
co-ordinates of the terminals)
4. place the resistor in the appropriate orientation returned by 3
5. connect the resistor to one terminal & place a wire between the
other terminal of the resistor to complete the circuit

Should i do the above in skill, or is there a fancy skil
function/expression to do the above?

Thanks
Partha
