Using VCarve Pro. How could I do something like this with the curved back and raised lettering?

I used the Wave_0.75 from Clipart 3D Tabs duplicated the component and put them side by side.
Created the Text (used Arial Bold)
Created a Boundary Vector around the two Components
Created a Finishing Toolpath selecting both the Components and Boundary Vector and selected "Selected Vector(s)" under Machining Limit Boundary.

1. You'll have to generate the wavy background outside of VCarve. It could be done in Aspire. You need an STL component that is just the background - don't worry about the letters, just get a smooth set of curves.
2. Import the stl,
3. Create text in whatever font you like using the text tool
4. Position the text over the stl import
5. Convert the text to vectors
6. Create an outline around the stl component
7. Select the outline and the text, then create a carving toolpath using the vectors as outline. This will carve the background but leave the letters proud. Unfortunately the letters will have rough edges, so...
8. Offset the letter vectors inwards very slightly
9. Create a profile toolpath with the same ballnose bit you used for the carving, cutting outside the offset letter vectors, and check the box to project the toolpath on the 3d model

I didn't actually run this, but I can't think of any missing steps right now. Try it and see if this gets you where you want.

Whoops!!! :oops: :oops:

Should read: Created a Finishing Toolpath selecting both the Text and Boundary Vector and selected "Selected Vector(s)" under Machining Limit Boundary.

Thank you both, I ended up using the method form Highpockets.

I created the text so it was flat across the top, not following the curve. I used the WAVE tab in one level and the RECTANGLE tab in another level. Along with the new clipping feature this was the result. And this was the result. By adjusting the rectangle tab height you can and increase the height the text is above the wave.

That "wave" looks like something that could be done with a moulding toolpath. (I'm not at my computer right now to try it.)

I experimented with this as detailed by highpockets. When I ran the file the roughing toolpath cut a different font size (smaller) than the finishing toolpath. I tried everything and finally by setting the boundary offset to -.01 I got what looks like the right result. I have not cut this out yet.
File is attached. Maybe I am doing something else wrong.

Change your boundary offset on the roughing toolpath to negative 1/2 the bit diameter,i.e. -0.125" with a 0.25" bit. The roughing toolpath uses the center of the bit for boundary offsets, whereas the finishing toolpath uses the edge of the bit for the offsets.
