Flexible Asm Issue Solved???

[Anonymous]

I think I've found a reason as to why there is a lot of trouble with flexible asm and the flying screws and such. I ran into the issue today, as well as many, many other times. I turned flexible and bam screws all over and nothing would move right. So I went in and flipped one of the asm over and re-tried flexible.....everything works fine. The trick to this seems to be, if you have similar asm or mutiple asm(s), they need to be facing the same way. ie, if your planes are on the top in one instance, they must be on the top in other instances as well...or you get wacky behavior. It must have something to do the 'normal' direction of the planes, if they are opposed....everything gets all screwy. Another time I have found issues is with the constraints themselves....like you accidently picked the hole axis instead of the hole axis. When in doubt delete the contraints..reconstrain..making sure you picked the right pieces. More often than not....the issuses go away. Anyone else notice similar things? Thanks, Larry

I hate when that happens. ;~)

I've noticed a few constraints flipping plane normals since upgrading.

LOL.......

fits better!

Larry,

When it happens next time, could you send me the files?
Thanks!

I don't know if this is related, but I had a problem with section views disappearing when I migrated drawings to 2008. I turned off visibility on some stuff and the view came back. I eventually narrowed it down to one or two pipe elbows in each case so far. Now, the first time I deleted the offending elbow and replaced it. (Then fixed my balloons.) Maybe I got lucky when reconstraining, because the most recent time I just swapped constraints, flipping the elbow. It didn't work every time, but replacing the elbow did in that instance.

If all the left to down elbows have the z-axis out, is that enough, or do the right to down's also have to as well? Would it help to have one of the part's planes line up with one of the assembly's ... or is that the real requirement?
