Hello Itzik, long time no chat! Are you ready for kickoff?

As far as the Datums, you will find that all datums have been turned off for this part.

You will have to click the icon above the model tree that looks like a sheet of paper and select "Layers Tree". Then select all the layers that are grayed out, RMB and select "Unhide".

Attached is the file with all those datums unhidden.

Further, if you RMB on "01__PRT_ALL_DTM_PLN", you will see that it has a Rule set to recursively look for new datum planes and add them to this layer. This is sometimes a useful tool for cleaning up the appearance or usability of parts and/or assemblies.

Please post if there are any further questions.

Good luck for the 2013 season!

Your version is an educational version so the full version cannot open your files.

I have had datums become "unstable" by which I mean inaccessible in some cases, and always visible in others regardless of hide state. This was always due to applying the ISO style datum tags. Adding a datum annotation to a plane makes them "unstable".

It could also be that you created the datum inside a feature and they become part of the feature and they hide themselves once the feature is accepted. The only time you can access these datums again is to edit the feature. I don't know how to make them accessible outside of that feature. it is similar to sketched hiding if they are created in a feature creation process.

Let us know if you find something else that may be causing this.
