Now, the next one is that our CAD standards state that whenever possible, all leaders should be drawn at the same angle...
That's getting REALLY anal, isnt' it?
...line up with each other (either vertically or horizontally)...
That's easy enough. Annotation will "snap" in line with other annotation.
...and have the same landing lengths.
See first comment.
I guess if you really HAD to have the same leader angles (although I don't see how that's possible on all drawings given the amount of notes on some sheets, but okay...) you create one then copy it around.
It's my boss's standard and honestly we tend to get our drawings through plan check faster and with fewer comments than our competitors, so he has to be doing something right.
No, it doesn't have to be the same on all sheets, just all leaders on that sheet (or as many as possible, obviously there will be exceptions to these rules).
Yes, creating one, then copy it around works, but is time consuming. Honestly, with AutoCAD, we can draw leaders to these standards very quickly., even without using LISP routines, thanks to some of the mLeader tools. I have created LISP routines that make it even faster though, so all in all it takes us less time to draw leaders to these standards in AutoCAD than it does to draw leaders that are not to these standards.
Annotation will snap, most of the time, but not always in our experience, I am not quite sure why it fails when it does.
