NX 7.5 Associative Datum plane(s) not automatically updating

[Johnasti]

I am wondering if anyone else has run into something similar to this with datum planes.

Creating a sample datum plane I have a series of datum points in space. I then create a datum plane based on the three points and create my sketch on said plane. I then edit the location of one of the datum points and I see a new point appear in the proper location, with the original point name/identity but there is also now a Vertex point where the original point was and my plane/sketch stay tied to that old vertex. Suppressing the datum plane and unsuppressing it again "fixes" the problem, the old vertex vanishes and the plane/sketch update to the new location of the datum point.

Any ideas on why this update is not happening automatically? Is it possibly a setting on my machine? Everything else seems to auto-update normally.

Thanks,
John

I'm afraid we would have to see an example part where this behavior is manifesting itself. I say this because I can't duplicate this behavior using NX 7.5.5.4.

John,

Here is a quick presentation with four slides showing what I am seeing. Thank you for any help you can give!

I'm confused, I thought you were simply positioning the plane of the datum using the three points. Now it appears that you're constraining your sketch using the points. But I went ahead and tried something like that as well and it's still working, so I'm afraid that without the part showing exactly what you're doing there is very little that I can do to help.

Sorry for the confusion there, I was just trying to break it down to the start/base level where I think the problem lays. I am attaching the .prt file I am working in. This is in 7.5.3.3. Hopefully you see the same things I do, but I am starting to think it is probably a setting issue on my end.

It works fine for me, using NX 7.5.5.4. Your next step is to contact GTAC and see if they can help. BTW, exactly how are you editing the parameters of the Points?

I have done both double-click on the point and right-click->edit parameters. Same result with both (I know it's the same thing but was trying everything I could think of). Thank you again for the help, I will look into getting in touch with GTAC!

 

[JohnRBaker]

Yes, I tried it both ways as well, just in case (when I use double-click I have it set to sutomatically do an 'Edit with Roll-Back' while doing a simple Edit-Parameters allows me to watch the entire model update as I make the edits).

I know this may not answer your update questions but. I have modified your part. Instead of having all of the reference planes. I have added a couple points and coordinate systems that may work for you. So instead of sketching on these reference planes you could use the coordinate systems to sketch on. I did not modifiy your sketch but just added the points between and coordinate systems. This is a trick I learned in I-Deas and it worked very well. Just a thought.
