gEDA-user: PCB footprint, Trimmer with hole in pcb at center

[Stefan Salewski <mail@xxxxxxxxxxxx>]

Hello,

there exits some trimmers which can be adjusted from top and from bottom
-- for the later we need a hole in the pcb.

I am not absolutely sure how the pin which makes this hole should be
defined. I did some search for examples at gedasymbols and in the wiki,
but there seems to be more than one way.

Simple make drill dia equal to outer pad dia? Use the hole flag -- or is
this flag for internal use of PCB only? Use "" for name and number?

For the following example I have used drill==thickness and set the hole
flag:
 
Element["" "" "TRIMR" "" 0 0 -13780 -21280 0 100 ""]
(
  Pin[-11811 -3937 7874 2000 9074 4921 "1" "1" ""]
  Pin[0 11811 7874 2000 9074 4921 "2" "2" ""]
  Pin[11811 -3937 7874 2000 9074 4921 "3" "3" ""]
  Pin[0 0 7874 2000 9074 7874 "" "" "hole"]
  ElementArc[0 0 13780 13780 5 62 1000]
  ElementArc[0 0 13780 13780 113 62 1000]
  ElementArc[0 0 13780 13780 222 96 1000]
  Attribute("comment" "arbitrary test data")
)

Is this correct?

Best regards

Stefan Salewski
