how to emboss and engrave text on any model/component in CATIA ?
This is a very weird method
start a draft
type in you text
save as dwg
open the saved dwg file
copy the text
paste it in the sketching plane in sketch while working on your part (the text is in black)
note: when you paste the text, you may not be able to see it. I recommend clicking on 'fit to window'
the newly inserted text can be transformed scaled etc.
exit sketcher. on this sketch you can do any operation you wish
