Each of the foundation elements has to be mapped separately into corresponding type of an isolated foundation, wall foundation or foundation slab. Read more about mapping process in Mapping.

Isolated foundation

An isolated foundation element defined in FEM-Design is imported to Revit project as a Structural foundation: Isolated element. Along with the geometry of an isolated foundation element, following properties are transferred:

  • Structural Material: mapping required.

Isolated foundation does not need a host element (e.g. column) to be imported to Revit.

*

Wall foundation

A wall foundation element defined in FEM-Design is imported to Revit project as a Structural foundation: Wall element. Along with the geometry of an isolated foundation element, following properties are transferred:

  • Structural Material: mapping required.

Wall foundation requires a host element in Revit - Structural wall therefore, wall foundations do not attached to a wall element in FEM-Design will not be exported (warning will be thrown). There are no properties of Wall foundation in Revit that would allow for setting the eccentricity therefore, eccentricity of wall foundation defined in FEM-Design will not be imported.

There is one recognized issue at the import of wall foundation. If wall foundations are added to a wall that contains a wall opening, after import of those elements to Revit, a wall foundation will also be added to the top edge of the opening.

Foundation slab

A foundation slab element defined in FEM-Design is imported to Revit project as a Structural foundation: Slab element. Along with the geometry of a foundation slab element, following properties are transferred:

  • Structural Material: as parameter of a floor type chosen at mapping.
  • Eccentricity: alignment settings from FEM-Design are imported to FEM-Design as z Projection parameter of an analytical foundation slab  element, according to the following rule:
    • Top /Left alignment from FD --> z Projection: Top of Element
    • Center alignment from FD --> z Projection: Center of Element

Be aware that a manual definition of an eccentricity value for a foundation slab in FEM-Design (e[m]) cannot be imported along with the foundation element.
