Danny, why did you provide aliases for some drawings and not others?
I've located what sheets the xrefs belong to. As far as renaming them, I am now finding out that they are all bits and pieces of an overall. So lets say sheet AA-101 has these xrefs in them
IMP-DrawingSheet-AA-101-BUILDINGALEVEL1FLOORPLAN-FloorPlan-A-1.dwg
IMP-DrawingSheet-AA-101-BUILDINGALEVEL1FLOORPLAN-IMPSiteandStream.rvt-1.dwg
IMP-DrawingSheet-AA-101-BUILDINGALEVEL1FLOORPLAN-PrincessKaiulani.rvt-1.dwg
the xrefs that has the "IMPSiteandStream" is pieces of the IMP-DrawingSheet-AS-101-OVERALLARCHITECTURALSITEPLAN-IMPSiteandStream.rvt-1.dwg
. An xref that is in sheet AS-101.
Also, the data is inconsistant: sometimes the full path and the alias is separated by one comma, other times 2
The full path came from Revit.
Makes it more onerous for a program to process than is necessary
I'm realizing this. Your help with the xopen and finding xref paths and info has been very helpful. At this point, I may have to go into every sheet to put together this puzzle. What makes things worse, the base points of all the xrefs are inconsistant as well.
Thanks for your help MP, I really do appreciate it.
