(One of) the methods of writing round and semi-round text for laser cutting and cutting on industrial parts
1- Select the desired arc or circle in AutoCAD software
2- Select the ArcText command by typing or writing Arc and select the second row ArcText
3- Select the arc and write the desired text and select the size and distances between the text and the location relative to the arc and all the settings that are available in the opened window.
4- Explode text from the Express Tools bar
5- Explode the text again and delete the extra lines (according to the video)
6- Save in DXF 2000 format and open the desired file with 3D software (for me it is Catia)
7- And now we have the rest of the events of adding volume or reducing volume to the text
