Tips

• Split Walls, Floors and Ceilings helps when one family holds several walls or slabs. Other tools can then select, measure and quantify each one.

• Use a named CPlane as Location to align the IFC with survey data or other consultants' models.

• Pick Ifc2X3 only when the receiving tool cannot read IFC4.

• Blocks are exported once as a type and placed as elements, which keeps files small.

The document units must be metres, centimetres, millimetres, feet or inches. Other units stop the export.
