Using the dome and text as an example.
Hide the text component.
Do a roughing and finish toolpath on the dome with outline of dome vector and outline of text selected. Use an negative boundary offset of just a little less than half the diameter of the tool that will be used to profile the text in the next step.
Create a profile toolpath of the text, set the Cut Depth to something really shallow .0001 and click Project toolpath onto 3D object.
To have the top of the text follow the dome:
Unhide the text component,
Do a roughing and finish toolpath, use the Selected Vector Machining Boundary with just the text vector selected.
Hope this makes since....
