Attachment Point change

Hi, people - some help, please.
Is there any trick to change the attachment point of an item without changing it's actual position relative to my body? I had a clash of attachment point for two items on my head so innocently thought that by noting the objects' co-ordinates I could attach one to a different vacant point on my head and just type in its original co-ordinates in edit mode to get it moved into the correct original position.
When I tried it - a hat with chin attachment point - it came in with a completely different orientation and so I had to plooter about with the axis icons in both move and rotate mode trying to achieve the original appearance. There's got to be an easier way......... doesn't there?
Also while I've got your attention - can anyone explain why in a lot of instances, I can enlarge an item in edit mode but can't shrink it any further than its original size in order to fit my 'petite' shape? Okay, for 'petite' read 'thin as a rake'! lol
Thanks

Sorry, but no. The item knows where it belongs in relation to its attachment point only. It does not care what that attachment point is, only where it is. So if you chage the point, you have to go into edit mode and postion it again.

The reason you can't shrink something beyond a certain point is that one of its prims has reached its minimum size (10mm). There are ways to make smaller prims (called "tortured" prims), but this is the minimum for a standard prim.

To shrink the object further, you have to select Edit Linked Parts and then NOT select whatever prim(s) are causing the problem. You will probably also have to reposition those prims after you finish editing the rest of the object.

i.e. it's a pain in the ass. I just deal with it.

In some cases, you can also locate the prims that are at 0.010 in at least one direction and sligtly increase that dimension, allowing you to then shrink the whole assembly further. For example, I have an obi for my Kimono that has one part that hit 0.010 thickness before I was able to shrink the linkset enough to fit a kid-sized avatar. I was able to locate and thicken that part, then could continue scaling the linkset down.

But it isn't always possible to locate ALL the parts that do this! I have a pair of roller skates that I absolutely can NOT locate the limiting piece in. I can't scale them small enough, and can't figure out which one(s) of the 50+ prims are the limiting factor.

Ok - thanks, people.
Guess the answer to the reducing question is just put on some weight so I don't need to shrink things!
The attachment point one is still a scunner - if it was just a case of using the axis co-ords to simply move it I wouldn't be so annoyed, but it's the fact that the whole orientation of the hat changed so it faced backwards at what looked to be approximately 90 deg to what it ought to be in the vertical, so there was a great deal of effort involved in achieving fluent swearing to accompany the less fluent reorientation!
Sod hats anyway!
lol

Yeah I never got why an item worn on the spine, stomach and pelvis could end up in 3 different orientations?

The axis coordinates are not global coordinates on the grid, they are relative to the actual attachment point. Stomach, pelvis and spine, for example, all attach in different places and moving the prim along any axis for each is moving relative the the point, not the grid as a whole. The axes for stomach are not the same as the axes for pelvis or spine.
