Yellow question marks in constraint navigator

[eex23]

Hi all,

please check attached few pictures. After loading assembly we can see yellow question marks in the constraint navigator. If you double click constraint with question mark it gives alert "unloaded references in the constraint cannot be retained in a redefine".
In assembly load options I checked option "load interpart data", but it seems doesnt help me. I think this happens then datums from "entire part" reference set are used to constrain components.
It is possible RMB on the question mark and select "load related geometry" and all question marks dissapears.
What option should be checked, to load related geometry automaticaly them assembly is opened?
Thank you.

Hi,

Looking at the below statement;

It is possible RMB on the question mark and select "load related geometry" and all question marks dissapears.

It looks like you still have unloaded geometry.
Check if you have below setting correct.
When you have the load interpart data checked, set it to "All Levels".

It is checked, check attached picture Nr.1, there is screenshot of load options dialog box.

It looks okay then. ( didn't notice the load options picture )

Of you have indeed constraints to datums which at a later point are hidden by a reference set then there will be an issue with the constraints.
The constraint will still be valid ofcourse (it is just a question mark, not an error showing) however when you want to edit the constraint you will need to load all geometry fully, which means also the datums hidden by reference sets. (switch to ref set entire part)

Thanks for the answer.

yes, I understand that these constraints are valid, but question marks also appears in the case then some components are not loaded, or geometry of these objects has changed. If you have quite big assembly with sub-sub-assemblies, it becomes complicated to understand which question marks are valid (just not loaded geometry), and which are not valid because of geometry changes.

Another annoying thing (not mentioned above), is exclamation sign in yellow triangle, then components are suppressed. Because you can also get exclamation sign then you have conflicting constraints. So it is not possible to get the point, then you get additional exclamation sign, which needs to be corrected, because of some conflict (strange that NX does not give you a message then some conflicting constraints appear).
