the best way to get a curve onto a surface is to use the project tool where you can sketch the shape on a 2D plane and then project that curve onto a surface

Hi

This is basicly the the same way as described by Carl but maybe it gives a better visual on how and where the curve on the surface is placed.

Another way is to place points on the surface you want to make a curve on and then using the spline command to make a curve and using the surface as support.

1. Drafting => Text - Enter your text.
2. Save your text as a dxf or dwg. (not quite sure what format, try them bouth)
3. enter in GSD (generative shape design), build your surface
4. In a different sketch insert your dxf or dwg (copy/paste)
5. project it on your surface
I dont remeber the command exactly but you can wrap your text on the surface.
For more details, please search on Youtube the bottel of Coke tutorial, I think that you will find it more explicit

Hope it helps :)

By creating a plane (tangent to surface)
