Comments
 If node_ID_{1} and node_ID_{2} are
defined, the symmetry will be done on the plane normal to the vector defined by
node_ID_{1} and node_ID_{2}. The
plane includes node_ID_{1}. If only one node is defined, the error message is displayed.
Otherwise, the symmetry will be done on the plane normal to the vector defined by point_1 and point_2. The plane includes the point_1.
 Transforms applied to node groups only transform the nodal coordinates. Material directions for orthotropic materials and boundary conditions such as initial velocity, imposed movement are not transformed.
