Hello!

i modeled the text like this... (no big secret:-))

extrude the text, boolean intersect with a slightly bigger circle than the sparkplug body...

thats all:-)

if the stretching of the letters is to big... because of the round body, i rotate the extruded letters a bit by hand...
and do than a boolean intersect...

after that i do a boolean differenz with a circle with the same radius as the sparkplugbody...


is this clear? (my english is a bit lousy:-)) hope the images shows it better:-)








best regards,

tijai
