Datum elements

In order to export datum elements, corresponding option has to be checked in the StruXML Export dialog.

Grids

Grids defined in Revit model may be exported to FEM-Design where they will be recognized as Axes. Grids are exported with following assumptions:

• If the option to Export Grids is selected, all the grids will be exported to FEM-Design.
• The exact length of the each grid is exported.
• All the grids are always exported into 00.000 m level in FEM-Design.
• Names of the grids are not exported, instead each axis in FEM-Design will receive a new number based on the order of grid creation in Revit (if necessary, renaming can be performed in FEM-Design).
• The maximum number of the grid in FEM-Design can be 1024.

In FEM-Design only straight line axes are allowed. Therefore,

• Multi-Segment Grid after export from Revit to FEM-Design will be replaced with a number of straight line axes equivalent to number of segment.
• Curved grid after export from Revit to FEM-Design will be replaced with a straight line axis between the start and end point of the original curved grid.

Levels

Levels defined in Revit model can be exported to FEM-Design, where they will be recognized as Storeys. Levels are exported with following assumptions:

• If the option to Export Levels is selected, all the levels will be exported to FEM-Design.
• Name of the levels are exported to FEM-Design.
• Size of the Storey in FEM-Design is calculated based on the placement of most outer elements in the Revit model and included as a Horizontal size of building in the Storey dialog.
• Levels cannot be exported if no elements are created in the Revit model (because size of a storey cannot be generated).

Reference planes

Reference planes defined in Revit model may be exported to FEM-Design where they will be recognized as Reference planes.

• If the option to Export Reference planes is selected, all the reference planes will be exported to FEM-Design.
• Name of the reference planes are exported to FEM-Design.
