hmtoggle_plus1Comments
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.In 3D, the skew is defined as follows:

node_ID1 and node_ID2 define Z’

node_ID1 and node_ID3 define X’

Y’ = Z’ ^ X’’

X’ = Y’ ^ Z’

3.When defining some conditions with respect to the skew in cylindrical coordinate system, the axis of the cylindrical coordinate system is assumed to pass through node N1.
