Offset Type

This section provides two options. You can set the offset as Global or Radial and Axial.

Global offset: This is a 3-dimensional offset which expands the machining faces in all directions.
Radial and Axial Offset: The Radial Offset is a 2-dimensional offset which expands the machining faces in the radial direction.
The Axial Offset is a 1-dimensional offset which expands the machining faces in the axial direction.

When you choose Global offset from the Offset type list, the fields of Axial and Radial offset are disabled and when you select Axial and Radial offset from the list, the field of Global offset is disabled.
