Overlap group and vector

[Doc986]

I have two groups (with two vectors, A and B, in both). The group 1 is over the group 2. But I want the vector B of the group 2 is up the group 1. How do?

Put group 2 on top? Put vector B into group 1?

If you put both groups into a 3rd one you can change layer ordering during animation. If you need just one element show up on top of the other group during animation, you may duplicate it, put it into the top group, and make it visible when needed.

I must try. Because the vectors in the 1 group are an hand and arm of a character. The vectors of the second group, are hand and arm of another character. So I can not move the vector between the two groups.

this seems to be an example of the "hold an object" problem - the hand that holds the object needs to be both above and below the item.

the usual answer is to create a duplicate and switch visibility.

Group A
- Switch A
-- hand empty
-- hand with object

Group B
- object

Time = 1: Switch A: hand empty
... >>> hand moves towards object
Time = t: Switch A: hand with object; Visibility Group B off.
... >>> "hand with object" moves ...

(e.g. object might be Character B's hand and they are shaking hands...)

Let me explain.
In Group A there are two vectors: a body and an arm (arm behind the body)
In gropu B thera are two vectors: a body and an arm (arm behind the body)

The group A is above the B.
Now, the arm B fight the body A.

In theory, the arm B should be above the body A, but is not so.
If I use your method, the arm B is above the body A but also above the body B (and not be so)

Understand my problem??

indeed - but to achieve what you want to do you need to redesign in some way.. overlaps are a very common problem. you can duplicate (parts of) structures and switch visibility between the "in front" and the "at the back" views. or you can use masking to hide parts of the "front" layers so that the "lower layers" show through them. but whatever you do you'll need additional layers.
