Hi Fledge2b,
You should be able to use SetOrigin. But I believe you are missing the first parameter. Did that compile?
See the definitiion:
/// <summary>
/// Sets the origin offset
/// </summary>
/// <param name="index">Origin index - 0 for G92 offsets, 1-9 for fixture offsets</param>
/// <param name="x">X offset</param>
/// <param name="y">Y offset</param>
/// <param name="z">Z offset</param>
/// <param name="a">a offset</param>
/// <param name="b">b offset</param>
/// <param name="c">c offset</param>
public void SetOrigin(int index, double x, double y, double z, double a, double b, double c)
HTH
