What setting controls the default Curve Rule for Intersection Point on all Point Contructor/Point Subfunction Type setting pulldowns?

For example, create a Point and from the Type pulldown, set it to Intersection Point. Now you should be able to see Selection Intent items appear and one of those is Curve Rule (along with Face Rule, etc.). Ours is continually set to Connected Curves, which is a pain because I constantly want line/line intersection, not a chain of curves! I change it, but it will eventually change back. Need to know where the default setting is to change it for good.

Thanks!

First off, there is NO way to preset this or many other defaults like it. One reason is that they are supposed to be remembered so they will remain set to how you last used them.

That being said, I can't duplicate the behavior that you claim to be seeing. When I create a Point at the Intersection of two Curves and if I set the Curev Rule to 'Single Curve' the next time I go to create an Intersection Point, it's still set to 'Single Curve'. Even if I exit NX and start another session, when I go to create an Intersection Point the Curve Rule is still set to 'Single Curve'.

However, I have to ask, even IF the Curve Rule WAS set to 'Connected Curves', what's the problem? If you selected a pair of single, unattached curves it would still work exactly the same. And even if it WAS part of a series of connected curves, again, who cares, it'll still work just the same.

Thank you for your response John.

Unless I'm not using this tool correctly, it's not behaving in the manner you describe in your very last sentence.

In the attached, the grey dashed curves (a pipe routing) are connected and tangent. The 2 green lines are additional lines that I added to illustrate the extended intersection of 2 of the lines in the routing. There is more than one bend in this routing.

I want a point at the intersection where the 2 green lines intersect, using only the grey dashed curves to construct the point. As you can see in image 2 (after I attempt to create a Point with Connected Curves) based upon the preview sphere location, that is where the Connected Curves deem the intersection lies. If I go ahead and click OK or Apply, it creates the point right where the sphere is located, which is not where the 2 green lines intersect. That is why I set my Curve Rule to Single Curve. Otherwise, it grabs the entire routing chain and isn't sure which intersection I want.

Thanks again for your time and help!

OK, in this case 'Single Curve' is probably the only usable workflow.

As for why your system is not retaining the last Curve Rule setting, I don't know what to say since I've opened and closed my copy of NX 8.0 several times and when I go back and check the Curve Rule when I create an Intersetion Point, it still comes-up 'Single Curve' every time. Does your settings change when you exit and restart NX? If so, go to...

Customer Defaults -> Gateway -> User Interface -> General

...and check the status of the 'Save Dialog Box Settings between Sessions' option near the bottom of the page. If it's not toggled ON, do so and then exit and restart NX and see if that corrects the problem.

The settings will revert back during the session - it will revert back without the dialog being dismissed. It reverts back after a restart as well, even with the Customer Default you mentioned above toggled to ON. Any ideas where on the Computer this information is saved? Registry, User Folder, etc.?

It's probably a permissions conflict - the I/T Dept. here locks down the computer so tight that I can't even remove icons from my Desktop. Another cause might be an old GRIP program changing settings after it runs - I noticed after running the program that my Displayed Decimal Places setting changes from 4 to 1. However, once I change that back, it stays. It's the Intersection Curve Rule that seems to get hosed at some point in time.
