# Specifying transition type (spline curve) (#AKIMA TRANS)

## Release Note

As of Build V2.11.2010.02 the command #AKIMA TRANS [...] replaces the command #SET ASPLINE MODE [...]. For compatibility reasons, this command is still available but it recommended not to use it in new NC programs.

Syntax:
#AKIMA TRANS [ [ START=<ident> END=<ident> ] ]

START=<ident> END=<ident> | Types of tangential transition between the spline curve and the adjacent (linear or circular) motion blocks. Specification of the transition types is optional. If no specification is made, the AUTO presetting is used. Permitted identifiers:
| AUTO | Tangent of the spline curve at the transition is automatically calculated
| TANGENTIAL | Tangential transition to the preceding or succeeding block
USER | Tangent of the spline curve at the transition is explicitly specified by the user

Examples of combining transition types 1 and 2

If an explicit tangent specification is selected for a certain transition (transition type 3) and if no tangent is programmed for a certain axis, this tangent is automatically determined (transition type 1).
