Mirrored Profiles

In the base product it is possible to set a mirror flag which implies that the profile is to be mirrored about the local Y axis, while keeping all other geometric attributes unchanged. Also you might wish to define a new arrangement of profile in the catalogue that would need mirroring before being written in the ABS file using the Orientation Mapping File. Under normal circumstances the ABS file would simply transfer a mirror flag, indicating what is required and how to interpret the geometric data.

Unfortunately, AVEVA Bocad Steel cannot handle mirroring, in any form. Therefore the ABSI interface has to handle all this internally before export, and after import. However, it is impossible to completely undo the transformations that have been performed on an element for export when the interface is re-importing the same element. For example: the ends might have been swapped round, or the end connectivity might be changed. In these situations the Compare/Merge might highlight a changed element even though it appears to occupy exactly the same location.
