I am trying to mill this with FreeCAD version V0.21.1:

3D Pocket gives me no tool path, how can I achieve this?
I selected these faces for the operation:

See also the report view here:

What can I do?
I don’t see how this can be sensibly milled from the top. Shouldn’t you rather turn Model-TestPart2 so that it can be milled from a different side?
What tools do you plan to use?
Do the 90 degree corners have to be as sharp as you drew them?
In the “Body to mill” image, I would machine in the Z direction with a pin cutter.

Forgot one thing, what is your CNC machine?
So we can give you the best possible answer.
Hi, thanks for your responses.
My my milling machine is this one: https://www.sorotec.de/shop/Compact-Line-assembled.html
Milling area is 600x400x170mm (X Y Z)
I am trying to make a finger joint for wooden panels of 18mm thickness.
I can only mill on the top surface of the panel, with panel flat on the machine.
If anyone has a better idea of making such joints with CNC, i would be very interested.

There are not better idea, it depends heavily in tool diameter, and you have to file them flush as the tool will leave some srcs when you have sharp corner un Z.
But this is the normal way cnc works.
Without tool data if tool diameter is large than the space between tenons path could not be done (but even this is not astonishing)
Kind Regards

If it must look exactly as drawn there is no 1 step solution.
If some gouging is acceptable at 90 degree corners this can be done with small diameter tools.
Everything would be much easier if it were possible to mount the part so that the teeth are in the direction of the Z axis.
