NX associative spline
NX associative spline
(OP)
NX 7.5-GM version...I could have sworn I have created associative splines before...maybe Im forgetting something.
In 3D not a sketch. Create a series of points, say 5, then create a spline through these points. Now move any of the points. The spline doesn't update to the new point position. I double click on the spline and change it to associative and delete the original. Move a point. Still the spline doesn't update. What am I missing?

RE: NX associative spline
Insert -> Curve -> Spline...
...and NOT...
Insert -> Curve -> Studio Spline...
...correct?
If so, WHY?
THAT 'spline' is NOT associative; never has been and never will be. It's a legacy command, which is why it does not show-up on the menu if you used one of the Roles which does NOT include full menus (and starting with NX 8.5, it won't be there even if you DO use a Role with full menus).
If you wish to create an associative Spline (outside the Sketcher) than the proper function to use is 'Studio Spline', period!

I wonder why the associativity option is not available on the basic Spline command at creation and what function the edit spline/associativity serves as it does not create the association you would expect.
RE: NX associative spline
When editing an Basic spline and turning on the associativity switch,
Since the old spline doesn't have the definition data stored ( which point objects) it cannot push that information into new associative spline. The newer and associative spline has the capability to become associative but it must not be associative. You can for example associate 3 of the splines 5 points to other objects and leave the other 2 free.
But , as you say if you create the spline using Studio Spline from start, it will immediately record what objects it snapped to and keep that associativity.

Note that is it true that since NX 7.5, if a user really wanted the 'Spline' icon to appear on the Curve toolbar, he could have used Customize to add it back, and while that will still be possible in NX 8.5, we have started to 'toll the bell' on it's eventual demise since if you do go to Customize you will see that the 'Spline' functions is now tagged with a 'to be retired' notation:
This process is how we go about obsolescing legacy functions which will no longer be enhanced and which are slated for eventual removal altogether.
So there, anyone who's still using this legacy 'Spline' function, YOU'VE BEEN WARNED!
