Default Orientations
There is a definition of the default orientation of profile shapes associated with the SDNF Specification produced by the Intergraph FrameWorks User Group. It is closely based on the AISC standard. It is proposed that each software package translates to this format on export and from this format on import. It would then provide a standard interpretation of the mirroring flags associated with Linear Members. The main issue here concerns angle profiles on import to Model.
The diagram displays the FrameWorks default orientations for the Catalogue profiles.
Note:
The FrameWorks coordinate system defining the Profiles is left-handed. There is a difference between this and the coordinate system used in AVEVA E3D™.
Mirror
Although the FrameWorks documentation mentions mirroring about both the X and Y axes, it can only handle mirroring about the Y axis.
Note:
The Cardinal Points about the Y axis are mirrored as well.
The interface does not handle mirroring about the X axis either. However, any desired result can be achieved just by rotations and mirroring about the Y axis.
