My biggest tip for using Auto Balloon would be the same as my biggest tip for using Auto Explode, Auto Dimension, and Auto Anything else. Don’t bother. OK, that may be a bit cynical of me, but practically speaking I’ve seldom, if ever, found much of SW’s “Auto” functionality to be very functional. Making a good, clear, exploded view drawing is nearly always a fiddly process for anything but the most simple assembly. Who’s it for? The guys building the assembly, or an end user looking for replacement parts? Or maybe just the guy who needs to make sure all the needed parts are in stock. The guy building the thing needs to clearly see how all the parts fit together and be able to tell what’s what. The guy looking for replacement parts isn’t too concerned with parts he can’t replace himself, or that you won’t sell him anyway. The guy keeping the parts room stocked wants to know exactly what, and how many, of each part are needed and most likely couldn’t care less what the assembly looks like. SW doesn’t know what you need the drawing for and it’s best guess at auto anything is, at best, no more than a starting point for you to make a usable drawing. I remember my SW instructor describing auto dimension as “shotgunning them on there”. So if just a few actually hitting the target is OK, shotgun away. If you actually need the balloons, dimensions, parts, etc. placed in a clear, organized way, break out the rifle, dial in the sites, and as my shooting coach used to say “Squeeze 'em easy.” (I.E. don’t jerk your trigger finger), one round at a time.
Admittedly some of it has probably improved since I last gave up on it, so I should go back and give it another try, but I’m not optimistic (not about that anyway).
Aaaand, rant over.
