Unless you are using a 4th or 5th axis then you can't machine 3D in one sitting. Best you can do is 2.5D without turning the work over to finish a true 3D object.
Even if you use Fusion to create a true 3D model the G-code it's spitting out will only be 2.5D code when using 3-axis and aspire will do everything fusion will in that respect.
Your only selecting the surfaces on a 3D model which can be accessed by a 3 axis interpolation, if you want to access undercuts etc of a true 3D model then you will need to re-fixture or add another axis or two.!
