as requested on support…

trying to take a piece 4.25 x 3.25 x .5 and mill it to the profile shown in the top figure of the attached sketch.

Measure the vertical dimension:

In order to model things it will be necessary to have geometry which is larger:

OK

Then model the arch — add the base height:

Scale the height:

The math and so forth doesn’t quite line up in the preview:

Adjusting the Stock thickness we get:

Compare this to the profile and adjust the angle:

Then align a copy of the original geometry:

Align

Ok

Draw in geometry around the desired model:

Subtract

Apply

Offset the original geometry by endmill diameter plus 10%:

Apply

Then set up 3D toolpaths:

To make setting the origin easier it would probably be easiest to use Center of stock.
