I have the same question as @wackolacko "Is it possible to get an associative angle measurement using Datum CSYS's using option 'Angle in WCS XY plane'? When this option is selected the 'OK' and 'Apply' are not available."

Wondering if you could help me with the specifics behind what @cowski suggested to do in the previous thread:
"As a workaround, you might try creating a datum plane on your current XY plane, create intersection curves between this new plane and your planes of interest, and finally create an associative measurement between these new lines. A bit of a kludge, but might work for what you want."

Not sure how I should define the planes of interest since previously I was just measuring from a components with the CSYS already oriented where I wanted it, then just measured to a vector where I got the 3 projected angle measurements in the information window. I am trying to simplify the angularity analysis on this components as it is frequently re-positioned, I'd like the 3d angle measurements XY, YZ, XZ. So I will most likely have to set this up three times for each angle.

Update: I tried to create an intersection curve between the two planes but I got a warning that intersection lines between two planes are not associative so this method may not work as the goal is to view the real-time changes in the expressions window.

I dont believe it is possible using the WCS reference. AFAIK getting an associative measurement requires you to use the absolute csys or a specified datum csys.

why is using the WCS a must here? I think this could be achieved using wave linked csys or if I am not mistaken, inter-part measurements are also possible.
unfortunately, I don't have NX11 installed anymore so I can't review that this actually works in NX11, however, the process should be quite similar.

Note that you can create an associative datum axis at the intersection of 2 planes.

Note that the original question is NX 7.5 and the original question was posted 11 years ago.

The WCS is not an object, It's not a feature , it doesn't have a timestamp.
It's a "freely movable 3D Ruler" without timestamp and therefore I doubt there are any features that can be associative to it.
You might see readings such as angle with reference to the current WCS but you will not be able to see associative readings.
you need to measure between "objects" to get the associativity.
