Couple of things to try
1) You can make a pocket on the 3D object then make the text in the bottom of the pocket
2) You can touch off the v-carve tool to the top of the 3D object and just engrave. The engraving will be on a flat plane and might look strange.
Aspire has a feature that we can project to a curved surface - but I don't think V-Carve Pro can do that.
