Both the supports and supports group defined in FEM-Design can be imported to Revit project. The exact support definition is imported to Revit as User boundary condition. There are however, substantial differences between the elements type that supports can be added to between FEM-Design and Revit. Please find the details in below paragraphs.

Point support and point support group

Point support and point support group defined in FEM-Design are imported to Revit project as Point Boundary Condition of a State: User.

Point boundary condition in Revit requires a host element and can only be applied to an end of a beam, column or brace element. Therefore, if a point support (group) in FEM-Design is applied to a wall or plate element, or not to an edge of linear element, or is independent, a warning informing about the lack of reference element will be thrown at the import.

There is one recognized issue about the import of point support group. If a point support group is defined in a local coordinate system of an element that is different than the global coordinate system of the FEM-Design model, and the stiffness of this point support group is not the same in all directions, an error will be thrown and this support will not be imported.

Line support and line support group

Line support and line support group defined in FEM-Design are imported to Revit project as Line Boundary Condition of a State: User.

Line boundary condition in Revit requires a host element and can be applied to a beam, column, wall and floor element. Therefore, if a line support (group) in FEM-Design is applied to a brace, or is independent, a warning informing about the invalid reference will be thrown at the import.

Surface support group

Surface support group defined in FEM-Design are imported to Revit project as Area Boundary Condition of a State: User.

Area boundary condition in Revit requires a host element and can be applied to a wall or a floor element. Therefore, if a surface support group in FEM-Design is independent, a warning informing about the lack of reference element will be thrown at the import.
