Which node should I refer?

Hi everyone,
How can I define a point as a reference frame which is located on the lower surface lumbar L1 segment and the frame should be parallel with the surface. In other word, the joint between a vertebrae and disc.

Hi,

You can use AnyRefNode object, where members sRel and ARel will define position and the orientation. For example:



AnyRefNode ExampleNode = {
  sRel = {0, 0.05, 0}; // 5cm in Y direction wrt. to the parent ref. frame
  ARel = RotMat(pi, z); // 180 degrees rotation about Z axis wrt. to the parent ref. frame
};
