About "Elements" of "Assembly3" used in "XYZ_Plane", please help!
When I use "XY_Plane, XZ_Plane, YZ_Plane" in "Elements"
"Assembly3" seems to be all identified as "XY_Plane"?

What are you trying to do?
It doesn't make sense to me...?
Can you, please explain better/in more detail

Re: About "Elements" of "Assembly3" used in "XYZ_Plane", please help!
when i use XYZ_Plane when alignment condition
in some cases
It is more convenient to calculate the distance from the center to the center
Picture 1 is
Body locked at (0,0,0)
Body001 at (100,100,100)
Picture 2 is
Body and Body001 use YZ_Plane as aligned Elements
After slove alignment
Body001 result should be (0,100,100)
But it's result...
Body001 at (100,100,0)

Why do you need or want to use body origin planes as elements???

In asymmetric Parts
Sometimes you need to use the center to align
Or use the center to calculate the relative distance
is more convenient
Anyway, XZ_Plane, YZ_Plane result is equivalent to XY_Plane
This should be a bug, right?
Re: About "Elements" of "Assembly3" used in "XYZ_Plane", please help!
You are doing it all wrong I am afraid
and, no there is no bug...
Explain to me what is the end result meant to be,
and I will modify your file.

PS:
Picture011 is
Use XY_Plane to align results
Picture012 is
Use "_Element" and "_Element001" to align results
I think under this sample
Align with XY_Plane
The result should be the same as Picture012,right?

with some of my comments in red, below
I suggest you do a (lot of) reading on this excellent page:

Picture 1 is
Body locked at (0,0,0) - locked constraint does not lock assembly part in a "postion" it locks it in relation to other parts of assembly
Body001 at (100,100,100) - doesn't matter where this part is, if the only constraint you use is PlaneAlignment, it can still be moved...
Picture 2 is
Body and Body001 use YZ_Plane as aligned Elements
After solve? alignment - there are still three degrees of freedom left....
Body001 result should be (0,100,100) - see above
But it's result...
Body001 at (100,100,0) - try using assembly mover and you will see that this is not true

"three degrees of freedom" is not important
if you care
I upload these two samples
Can you tell me why using XY_Plane is wrong?
The result should be
X distance 0mm
Y distance -100mm
Z distance -100mm
Shouldn't the results for the two samples be the same?

Re: About "Elements" of "Assembly3" used in "XYZ_Plane", please help!
The point I am confused about is
Why are all XYZ_PLANE displayed on XY_PLANE?
