You can use the Q3RotateAboutPointTransform_SetAngle function to set the angle of a rotate-about-point transform.

TQ3Status Q3RotateAboutPointTransform_SetAngle (
TQ3TransformObject transform, 
float radians);

transform

A rotate-about-point transform.

radians

The desired angle, in radians, of the specified rotate-about-point transform.

DESCRIPTION

The Q3RotateAboutPointTransform_SetAngle function sets the angle of rotation for the rotate-about-point transform specified by the transform parameter to the value passed in the radians parameter.
