Fixed view error. (for now!) What did I do?
1. Checked out entire assembly (used for drawing base view), and all its sub sub sub sub parts.
2. Used Task Manager to Migrate files (enabled options: total rebuild, compact model history, purge data; disabled skip files), not from Vault. Processed 500 files or so, no errors!
3. Open base assembly iam, dove into most likely sub part, it is a composite body (from import stp/igs most likely), with 534 'bodies' that were all run thru repair environment, and find errors found nothing. Save, close, up 1 level update, save, close, repeat to top level base assembly, update save
4. Clicked manage total rebuild, and update mass. Save.
thats about all the file cleanup tricks i have, so I opend the idw, and changed the view from feet only, to full hubs and feet. The view redrew and all entities became visible. Moved detail call out, resized, and anchored, view stayed without error.
Good Luck everybody.
