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. This is closely based on the AISC standard. It is proposed that each software package will translate to this format on export and from this format on import. This would then provide a standard interpretation of the mirroring flags associated with Linear Members. The main issue here concerns angle profiles on import to Design.
Below is a diagram showing the FrameWorks default orientations of the Catalogue profiles.
Note:
The FrameWorks coordinate system defining the Profiles is left-handed. The difference between this and the coordinate system used in AVEVA E3D™ is illustrated by the diagram below.
Mirroring
Although the FrameWorks documentation mentions mirroring about both the X and Y axes, it can only handle mirroring about the Y axis. The results of mirroring about the Y axis are shown below.
Note:
This also mirrors the Cardinal Points about the Y axis as well.
This 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.
