NX6: isoparametric curve through point ? 2

[opetrenko1]

is it possible to extract isoparametric curve passing through a point in NX6?
Thanks

That specific functionality was implemented in NX 8.0 when we enhanced the Isoparametric Curve function to allow the selection of a specific point on a face, along with several other enhancements, including making Isoparametric Curves a fully functional feature associated with face being selected.

About the best that you can do today (with NX 7.5 or older versions of NX) is to first determine the U/V location of the point of interest on a Face and then manually enter those values into the current Isoparametric Curve creation function.

Now you could write a simple program which would allow the selection of a point on a face, extract the U/V parameters of this point and then create an Isoparametric Curve on that same face using these derived U/V values.

Thank you John,

Could you point me in the direction, where I'd start with creating such program or at least the name of the API.
Thanks

Johns statement is not entirely true. When you have selected the face , in NX6, you can select points ( instead of specifying percentages) and create the isoparametric curve through that point.
See attached image.

I know that it can be done using GRIP, so I would expect that it wouldn't be a problem using NX Open (AKA User Function). Now as to whether it could be done using a Journal, I'm not so sure as there is no actual interactive function which will return the U/V parameters of a face based on selecting an existing Point object.

BTW, can you execute GRIP programs?

Toost is correct. I hadn't used this function for awhile and had lost track of exactly how it worked. I guess it's true what they say, When you get older your memory is the second thing that goes... ;-)

Hi,
I am a little forgetful about NX6 but i guess if you have a shape studio license then SECTION ANALYSIS too can be used for creating isoparam passing through a point.

Toost, your solution works. Thank you.
John, yes grip works. I'll start digging help on it, as I run into problems requiring automation. Thank you.
