Today one of my PCB designs suddenly lost all net assignments in the PCB editor. Is this a known issue with AD? Luckily this board was auto routed so there will be little work to be redone.
Edit: I recovered a good version via the 'history folder'. Good feature to save all previous versions. Thank you Altium...
Re: ALtium Designer: Suddenly loses all net assignments in P
No, it is not a general problem with AD. Your file must have somehow been damaged. Another way to have recovered the nets would have been to simply gone back to your schematic and used Design>>Update PCB Document. That should have restored the nets.
No - the same kind of file damage can result at random with any WINDOWS program. The software engineers have anticipated the possibility, and provided automatic backup capability that allows you to recover from Microsoft problems like this.
If you start avoiding software because it might damage a file, you better quit computing altogether.
