Ah, okay - I think you have nailed my problem - I used to be able to search all Vectorworks files but can't any more...
But thinking about it, it might be that my OLD version could do this, but 2017 can't, so it's a failure caused by upgrading...
I need a solution somehow, because there are a lot of symbols that I only use sometimes...
Would it work if I copied all the old symbols into a single file? If so, where should that file be placed?
Thanks!
