Recessed Finger Pull

Short question!
What would be the best way to create a recessed finger pull for a box as in the image below?

Lots of ways. One is using the Levels Clipping option with an dome shape.

Just updated my post.
It's not hard at all. I'll look for the video link on Level Clipping....

First thing though, do you have VCP v10?

Here's another way using the Moulding Toolpath.

Create a very small half circle and a quarter oval to represent the finger pull profile.

Thanks, buddy
I'll have to look into this level clipping a little more, looks a very handy asset to be able to perform.
I only have V Carve Desktop v10.016
From the vid you sent, it seems that I have the capability within my software package, so I might as well learn it.
Much appreciated for your time and trouble in helping me out

And another method using the Fluting toolpath.

I drew a horizontal line from the outside top right to the center of the pull.
Made a circular array of copies. Rotation center at the left end of the line, Rotate Copies box checked, 41 copies, Total Angle 184.5. Node edit to be sure the start point is on the outside end of each of the lines.

Notes:
1. The fluting toolpath causes the center of the bit to follow the vector. So, if you use a 1/4" end mill, it will cut 1/8" beyond the end of the vectors. If you want the pull to have a radius of 1" and you are using a 1/4" end mill, the vectors should be 7/8" long. And the length of the pull will be 1 1/8, not an exact circle.

2. When you use the fluting toolpath to cut a curved surface like this, I've found that if the maximum distance between vectors is about 1/4 of the end mill diameter, the resulting surface is satisfactorily smooth. You can experiment with other vector spacing if you wish to reduce the cutting time.

3. The circular array leaves a space after the last vector. So to get a full array of vectors, the total angle has to be Angle desired + Angle/(no. of vectors - 1). In this case, it was 180 + (180/40)

4. The picture used 61 vectors, but 41 vectors should be satisfactory and take less time.
