How can I Mill a Half Sphere form.

I suspect the problem with Vcarve was that two objects were introduced and had a Boolean union taken place it might have worked.I did a rough and ready test to prove it can be done.First a sphere embedded in a cube.Then the Boolean dialogue.Switch to Path workbench and set the relevant preferences.Create tool controllers.Select parameters to suit your machine-these are just examples.Pick the operations you intend to carry out and work through the parameters-it may take more than one go to get them accepted and yu may want to play with boundaries.You should see a display showing the result and it renders much faster in wireframe mode.Reducing the accuracy of the simulation is a good idea because it can take a very long time.
