Creates a FEM constraint for keeping the nodes in a planar surface in the same plane.


  1. Click on FEM ConstraintPlaneRotation.png or choose ModelMechanical ConstraintsFEM ConstraintPlaneRotation.png Constraint plane rotation from the top menu.
  2. Select in the 3D view the object the constraint should be applied to, which can be a face.


  1. Plane rotation constraint can only be applied to a single planar face.
  2. When a plane rotation constraint is applied to the same face as a displacement/fixed constraint, the displacement/fixed constraint takes preference.


  1. The constraint uses the *MPC card in CalculiX. The card is explained in detail at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node220.html
