Composite reference surfaces not updating

[Anonymous]

Autodesk Inventor 2015.

Vault 2015.

I am having a bit of a top down modelling problem (I think that is how one would describe it).  I have attached some general pictures for reference. 

The 'top' picture has objects in context. 

The 'conveyor' picture displayes the reference assembly.

The 'surfaces' picture displays the conveyor and some structural surfaces in the assembly which is to be 'built' around those surfaces.

Most of the objects are heavily stylised and are just to demonstrate the space is either occupied or available as a mounting surface.  The design intent is that as the concept evolves and is improved the information and detail of things like the conveyor placeholders will increase / change.  These changes should obviously carry through to the assembly where those size / positions are important / needed.

I am not sure how obvious it is, but the roller has been moved forward in the basic conveyor frame, yet this simple change has not carried through?  I realise there are other additions into the space which I would need to tell the programe now exist and should be maintained.  Just I don't see the point of progressing with this type of design approach if an adaptive suface reference well isn't... adaptive?

To be clear the 'update' button is greyed out indicated everything is 'updated' although clearly not.

Currently I am admitedly concerned that I might have just enough knowledge about adaptive surfaces etc to be nothing but dangerous (and like the other draughtsman I should just give up and use only bottom up design).  From a logical cooperative design team perspective I would think what I was trying to do was correct, in that a conveyor somewhere could be worked on by a seperate design team and I should be able to update that changing information into my part of the overall design solution.

Why is this not updating?  What am I doing wrong?  How should I be approaching this intended design philosophy?  Should I just stick with a bottom up approach (especially as trying to think ahead as to how what might change does make early modellingstages hard)?

Hi! Have you tried Manage -> Rebuild All? Does it help fix problem? If yes, it could be related to out of sync update (or lazy update) behavior. It looks like you have adaptive subassembly (in-context)  which is also used in derive workflow (out of context). If a component requires both in-context and out-of-context update, Inventor can get confused. This seems like a dataset specific behavior. Could you post it here or send it to me directly (johnson.shiue@autodesk.com)? I would like to take a look and see if there is anything not working as intended

Many thanks!
