I think F.Fab and B.Fab is what you want. Reference designator is supported using 
"REF**"

(I guess this mailinglist might be the wrong place for this discussion
now, but...)

So, I tried adding a text string to the component (in the footprint
editor) with REF** on the
F.Fab layer.  Afterwards I did change the footprints in the PCB
schematics, and now I
see REF** on the F.Fab layer, and not the actual reference designator.
I'm using a nightly build
that is 14 days old...


Odd Ref** should work.

But you can also try %R

You can take a look at the kicad library convention [1]. There we 
require the use of a second reference on the fab layer.


You can even look at a footprint of the standard lib that has this 
implemented. I could suggest the R_0805 [2] resistor from the 
Resistors_SMD lib.

If I were you, I would use F.Fab and B.Fab for this purpose.

Yes, you can use %R (reference) and %V (value).

This is the developers mailing list.  You should use the user's forum at
https://forum.kicad.info/.  Typically user questions have a better
chance of being answered there.

You need to use %R for the reference and %V for the value.

I think F.Fab and B.Fab is what you want. Reference designator is supported 
using "REF**"

[Kicad-developers] PCBNew / Footprint editor - "Special strings"

[Thomas Langås]

Disclaimer: I come from the world of Altium, and might have a biased workflow.

Is the following possible in any way in KiCad, or is there a different
workflow that
supports what I want?

Usually, when I make components, I have a mechanical layer called
"Assembly" where I either duplicate the silkscreen, or make a new
symbol (not all components have silkscreen). In addition,
I add a text label which contains the value  .Designator .  This ends
up being translated to the
component reference designator in the end.  This way, I have a layer
containing nothing but assembly information.  This is *very* useful on
designs where space is so limited that it's
impossible to have the ref des in the silkscreen, for instance.

Summary:
- Does KiCad support having an F.Assembly and B.Assembly layer?
- Does KiCad support "special strings" like Altium's .Designator ?
