NX6 Assembly Constriants - Infer Center Axis

NX6 Assembly Constriants - Infer Center Axis

NX6 Assembly Constriants - Infer Center Axis

(OP)
Background:
Working in  NX6.0.5.3 MP3

Our previous part fams were built on mating conditions.  I am new to the role and was asked to lead up the NX6 implementaiton to our site(serves app. 400 daily NX users). NX6 was deployed sucessfuly and we have been using it since June.  I am now trying to capture items that slipped through as well as plan for the future with what I saw at the regional PLM conference.  

I applaud the Reuse library and have been working as one of my main goals to populate this with everything that I can think of based off of our site standards and commonly used items. But in the conversion of our part fams, I am having an issue updating some of the assy constraints.

Questions:
1)When using a simple item such as a NAS623 screw(Touch and Align constraint), is there a way to force the remembrance of the axial geometry "Infer Center/Axis" during installation so that users do not have to select the dropdown each time or get the component placed tangent to the hole and not completely aligned?

2)Since I could not get this easily working through multiple attempts, I tried to use the concentric and touch align constraints when rebuilding my part fams.  At this point, when both constraints are present, it says that I am overconstrianed. Below are my information windows on the constraints.  Am I not properly understanding how the concentric constriant should function with others or do I have an issue with my model that does not allow me to select the cylindrical face of the shank of the fastener?

@JohnBaker
I enjoyed and learned some cool stuff about NX7.5 at the recent Houston conference that I want to implement here, but its just me pushing the envelope right now!(with little to no money inside of course) :)

Thanks all

RE: NX6 Assembly Constriants - Infer Center Axis

Kenny,

Are you saying that using Remembered Constraints doesn't work ?

Remembering constraints works, but the axial geometry isn't "keeping".  It always defaults to "Use Geometry" when I want it to stay as "infer center/axis" for my Align constriant.

If using Concentric, just select a circular edge on each part. It then makes the edges concentric AND co-planar.
