Comments

  1. Moving skew defines a local coordinate system, defined by three nodes. At each time, the actual orientation of the skew is recalculated according to the actual position of these nodes.
  2. For moving skews, the skew system is moving and is defined by node identifiers node_ID1, node_ID2 and node_ID3.
    The axis definition depends on the input for Dir.
