I’ve been quite comfortable using blocks for a while but am sure I don’t use them in the most proficient way. Recently I have started inserting building elevations and to model each in, which I then insert into an assembly file (as per a Simply Rhino video tutorial).
However when connecting these files together many, many layer stack up and are only deleted if purged and then reopened.
But whilst carrying this out somehow one of my linked (inserted) files has had the contents deleted, erasing all the roofscape and walls with rooflights etc.
This took a looong time to create. But why has the file been lost?
I’ve tried reverting to previous versions but they skip back 4 hours even though I save the file with my left hand every minute unconsciously…
How do I recover this work please?
