These settings can be used to fine-tune the Spline Arc object or to create slight variations of the Spline Arc with modified settings (**New Transform** command in the Tool menu).

However, note that links to existing spline points might be lost if settings other than **Center** and **Middle Point** are modified. Additional segments will then be created. The coordinates defined here relate to the world coordinate system.
