Let me get this out of my system.

DO NOT USE ASSEMBLY CUTS OR FEATURES IN PRO/E

They cause all sorts of reference issues and if you select the wrong options when creating them you can cause all sorts of problems. This is more of an issue when multiple people are working on an assembly but the consequences are sitll the same. This is the easiest way to cause a cicular reference and should only be done as a last resort.

Now that I've had my soap box speech what type of feature you want to create really drive how you should do this. Make sure to not check the modify part option when when making an assy cut if you don't want it to effect individual parts, this is where the the references that cause issues get created. The reason I suggest not doing this is from personal past history of large assemblies crashing from circular refs. The problem is not the commands but the inability of most people to use them properly. If you are are careful and read all the prompts you won't have any probelms. I still however never let designers or other engineers working on my program do this.
