Prime perfectly aligned but still edges overlap?

I'm having a dickens of a time with object alignment, please see image here:



See the object parameters, they are perfectly aligned and yet one still overlaps the other. Why is that? I see this on every computer i log in with, it is not anti-aliasing edges but the object is actually not 'really' aligned despite the object parameters saying otherwise.

Why? Anyone have any suggestions how to fix this?


Thanks.

Are they really aligned is the question I would ask? Unless you type the numeric values in yourself, they may be off by a fraction that the viewer won't display.

To get around this is easy. If you want them aligned, snap them to a grid boundary, then select them both to move them into the position you want.

The thing that makes me suspect this is the X coordinated with the .539 value... It may be .53998 in one and .5395 in the other or something equally not identical :)

Hope this helps!

That was the first thing I did to make sure, but still it overlaps. I ended up creating two new prims bcuz no matter what, those other two wouldn't align even when I did as you suggested.

Are you certain your texture doesn't have a thin strip of transparent pixels on one edge?

I am experiencing this problem lately, I had the same problem some time back too, for me I find its intermittent and depends which sim/sandbox I'm building in. I make a floor, it's perfect no edge overlap, no slight edge layer flickering, then the next day rez it and it looks like it's been build by a blind man. I'm sure some sims are just bad for prim drift too.

i made some quick experiments and i found, that on our SIM everything is ok, as long as the objects can be aligned on a 10 cm grid in x,y. smaller grids lead to more missalignment.

i.,e. your objects would be perfectly aligned if they where placed at:

x:153.5, y:232.0, z:21.81
x:153.5, y:232.0, z:20.81

I tested it using unit cubes. maybe things vary when you use different sized objects.
Now the weird thing is, that once they are aligned, they stay aligned if i link them and i move them alltogether to any position.

So maybe the rule is something like: "build on a low resolution grid, then move
the linked parts to their final destination" ?

just my 2 cents here ;-)
