This is a new one for me,
I'm working on a drawing with several hundred light fixtures, and I was number fixtures one truss at a time. I did a set of fixtures on a truss and I realised I missed one. So I selected all the fixtures again including the missing one, and did number instruments. The number started in the tweties. I've tried it on other trusses as well, and it starting a different numbers each time. My latest try started at 19 is skipping number randomly:19,21,24,31,35,38,39,44,47,61,64,65,73 ...
WOW
Anybody ever seen this?
I can use the manual method, but it takes time.
