I don’t think this would be very easy to fix manually. I did it with Ruby.
There were 6607 components with geometry more than 1km from the origin. One of these I looked at had zero length edges, I only looked at one, there could be thousands.
This text file has a list of all the problem components:
Components outside 1km.txt (238.6 KB)
Here’s my ‘fixed’ version with 6k components removed. It’s only 13MB now:
I have a feeling that you’re losing something by deleting all these components. Were they models of tiny surface mount components? Maybe they got corrupted in the export/import process somehow.
sWilliams just posted while I was pasting this here, I haven’t looked at that yet.
