There is a utility you can download from the front panel express
website for designing dials, arcs, and so forth.

"Can anyone give me some pointers on creating a 150 degree arc label for
a band switch for Front Panel Express? I have a radio switch 86 switch
with 30 degree detents. 6 positions, 160-10 meters."
If an actual arc is needed, you can select "Insert Curved Slot" from the
menu. Then select the engraving width/depth (e.g., cutter 0.6mm). The
slot can be rotated, expanded, degrees set, etc.
To set up 30-degree index positions (and optionally with with engraved
lines radiating from center), you can use trig functions on Cartesian
coordinates. For all switches, I used the switch center hole as the
Cartesian origin. Once you decide on the distance to engrave from the
switch center -- and you already know the angle, then solve for (X, Y).
Take the computed X coordinate and add it to the the origin's X
coordinate. Do the same computation for the Y coordinate.
When recently solving this for a 2-position switch, I wanted to take
advantage of the switch's locking tab and insert it into a blind hole on
the panel reverse side. So that the position center center lined up
vertically, this meant that position 1 is 15 degrees left of vertical and
position 2 is 15 degrees right. Instead of solving by using the actual 30
degree arc, it was easier to solve using 15 degrees.
You're welcome to my panel file if you want to have a look.
