Good evening@mbabaoui
Very simple and fast
In the top tabs
- Select Tools
- Click on Customize
- Orders tab
- Duties
- You have the Dome icon which is in the second column, 4th row
- You click, drop the icon in your toolbar, you validate and that's it.
I specify -but you should know- that this only works from an existing extrusion so put your Icon in the Function tab instead (but can drop it elsewhere but if the place you choose is not possible SW will refuse with a nice red cross.)
Kind regards
