Exporting IFC data for structural grids
If you use the Grid Line, Grid - Polar, or Grid - Rectangular tool to create a structural grid, Vectorworks automatically assigns all the necessary IFC data types and values to the grid and axes.
IFC grids are associated with their design layer at export. Up to three grid sequences on a layer are automatically combined into a grid and exported as IfcGrid. Individual grid lines created with the Grid Line tool are exported as IfcGridAxis. The first grid sequence on a layer becomes the UAxes collection, and every grid line in that sequence is exported as IfcGridAxis from the UAxes collection. The second grid sequence (if one exists) on the layer exports as VAxes, and the third grid sequence (if one exists) on the layer exports as WAxes. To be compliant with IFC, there can be no more than three grid sequences on a design layer; any additional grid sequences on a layer are omitted from the export. Place additional grid sequences on other layers to ensure they export correctly.
