I have recently started using SW2015 and was working on some old SW2013 files when i was prompted some errors (capture 02 Error.jpg)
All the fasteners are having rebuild errors and in this case, the bolts are all different. The head is very much bigger. I tried deleting the fasteners and insert a new one from the toolbox, the bolts are the same.
Please advice if there's any problem with the toolbox installation?
