Export of IFC4-consistent reinforcement

The Export IFC Data tool uses the new IFC 4 interface to transfer reinforcement in a complex manner for the formats IFC4 and IFC2x3. To transfer reinforcement, select the IFC4-consistent reinforcement geometry option in the IFC Export, Import Settings dialog box.

The reinforcement is described as a swept disc solid consisting of a circular disc for the bar cross-section and the path for extrusion. Select this option to transfer the path for extrusion as an indexed poly curve. Otherwise, the path will be transferred as a polyline.
