You can use the Q3RotateAboutAxisTransform_SetOrientation function to set the orientation of the axis of rotation of a rotate-about-axis transform.

TQ3Status Q3RotateAboutAxisTransform_SetOrientation (
TQ3TransformObject transform, 
const TQ3Vector3D *axis);

transform

A rotate-about-axis transform.

axis

The desired orientation of the axis of the specified rotate-about-axis transform. This vector must be normalized.

DESCRIPTION

The Q3RotateAboutAxisTransform_SetOrientation function sets orientation of the axis of rotation for the rotate-about-axis transform specified by the transform parameter to the value passed in the axis parameter.
