Hi, I would like to create a part by assigning pin numbers and reference designator number to a building blocks/parts instead of creating this part in editor. Please advice if there is a way in KiCad to get this.
too vague, to cryptic…
We? (at least I) need more info than that.
What kind of workflow do you have in mind?
Anything people could have a look at (video, screenshots, etc. pp)?
What editor we’re talking here btw… schematic or footprint?
Attached is a letter that provides more specifics regarding my question

Hehe, not so formal, really no need to pack this up in a pdf
I tried to do something along the lines of what you want, but I think it will fail once you try to get more than 26 pins for a single connector via the Number of units per package option (when you create a new symbol). And with that the whole way of doing your connector as an arbitrary/adjustable number of schematic symbols falls flat on it’s face as you can’t have the reference appear more than once in a schematic. With the units per package option you would had been able to work around that a bit I think, but it’s just got 26 as maximum option… maybe you can find a programmer (or do it yourself) and raise that limit.?!
As you can see the netlits would be somewhat useable… but you could only have like 26 pins for connector ‘D1’ which wouldn’t be enough for your use case.
Thank you for explaining system limitation, but this lead to the legit question do you have on to do list a task to increase the number of units.
And the question I asked in the beginning: is it possible, for the connector, by typing pin name to force system to bring pin (number) corresponding to the name?
Thanks
I’m just a user who answers questions in a public forum to the best of his knowledge, sorry.
If you want to get the attention of the Devs to this you have to use the bugtracker and add a feature request afaik: https://bugs.launchpad.net/kicad (yes, needs new user application over there)
Pin number and Pin name for a symbol in eeschema have different weights…
The number is the important part and relates the schematic circuitry over to the pcb layout… it’s THE thing that is used for the netlist.
The name is really just for our own reference what this pin does or is for. No real relevance for anything.
Both are independent of each other afaik.
The other important ID is the Field Reference… as this relates the whole symbol to the IC or whatever you use on the PCB.
The problem you got is that you want/need the Field Reference for 300 schematic single pin symbols to be the same and KiCAD isn’t built for that.
You can do what you want by either getting the Number of Units per package increased or suck it up and create symbols for each of your 300-pin connectors…
Those are the choices.
