Searching for constrain sets

Hi, we work with big assemblies and sometimes structure of the model is a mess.
I want to find which part position will be affected after i change constraint of specific part(move). This is downstream example.

Next case is I want to know which part placement will affect this part position. This is upstream example. 

How can i do it in creo? 
Thanks in advice)

The reference viewer supports such queries. Use the RMB in the model tree on the component of interest to activate the reference viewer as shown below.

Then set the context of the reference viewer to current component placement feature as seen here.

Yes, you are right it is actually possible to find constraint this way. But only one level further. And also when working on assebmly level you don't want to know which feature is creating this constraint. Most of the time(99.999%) you want to know which surface or which part is making constraint.
But this feature... it does something i don't know how to describe. It is unreadable. 

For example:
In this case i've modeleed simple boxy thing and connected everything with coinsident constraints. Each box has 3 mating surfaces with previous one. 
For some reason there is 4 reference surfaces from 1 extrude. But I've made mating by coinsident constraint with only 3 of them. 
Next problem that i can see from here is that there is no children found. But if you look at the model it is obvious that next box is connected to the one I've highlited.

I think I know why there are 4 surfaces documented for your case, I would need the models to confirm. Are you able to share your test model? I have Creo 7 and Creo 9 installed.

 

If you hover the mouse pointer over each of the surfaces it will highlight them in the graphics window. By doing this you may understand why there are four surfaces used to define the constraints (references).
