4.1 Project data
1. Export General project data to IfcProject
This tick box triggers export of the data defined in the tab "General" in Project data, which is accessed via Preferences > Project data > General.
2. Project location
Here you can choose whether the address and or the coordinates should be exported to IfcSite. Coordinates and address are defined in the tab "Project location" via Preferences > Project data > Project location.
3. True north
This exports the angle value between local Y axis and North to "IfcGeometricRepresentationContext". The value of this angle in degrees can be specified under Preferences > Global nil point.
Important:
Depending on the import setting of the IFC recipient, the export can have a major impact. If the information in the "Geometric Representation Context" is taken into account in the recipient software and the object is physically rotated via the object placement when exporting the file, this can result in a double rotation. Therefore, always define, agree and carry out a test exchange beforehand!
