Structure Constraint Icons
The constraint icon shows which degrees of freedom you constrained.
Two rows of boxes appear at the base of the triangle, with each box representing a degree of freedom. The degree of freedom represented by each box varies depending on the type of coordinate system, as shown below:
Cartesian:
Trans X
Trans Y
Trans Z
Rot X
Rot Y
Rot Z
Cylindrical:
Trans R
Trans T
Trans Z
Rot R
Rot T
Rot Z
Spherical:
Trans R
Trans T
Trans P
Rot R
Rot T
Rot P
Filled boxes correspond to constrained degrees of freedom or enforced displacements. Empty boxes correspond to degrees of freedom designated as free.
In this example, the current coordinate system is Cartesian and the constraint is fixed in Trans X, Trans Y, and Rot Z:
This icon indicates cyclic symmetry constraints. The icon appears on your design at the axis of symmetry:
This icon indicates mirror symmetry constraints:
This icon indicates Along Surface constraints in FEM mode. The icon appears on your design at the reference surface:
