NX7.5 Expression or Function to Display absolute coordinates of Object

NX7.5 Expression or Function to Display absolute coordinates of Object

NX7.5 Expression or Function to Display absolute coordinates of Object

(OP)
I am trying to create a drafting note that will display the absolute coordinates of a point.

I have a tooling ball assembly that contains 3 parts; The tooling ball(with a point at its center), the tooling ball cover, and a tag plate with coordinates (drafting note) that displays x,y,z locations. *I have attached the assembly so you can get a better understanding of what I am trying to accomplish.

Currently we have to bring the tooling ball assembly into the design, wave link them into a part, make the that part 'displayed part' and perform an 'Information > Point' on each one.
Then we have to manually copy the coordinates from the popup NX notepad window, and manually enter them into each of the tags drafting note.
Needless to say.. this takes a lot of time! Especially when we have 3 or 4 parts in an assembly, each one needing three tooling balls!

Is there anyway to tie the location of the point within the tooling ball to the drafting note in the tag?

I have played around with expressions and relationships a bit but all I've managed to do is display distance between the point and a datum, but the result is always positive.
For example I would like it to display like;

X =  900.000
Y = -760.000
Z =  320.000
(3 places after decimal)

Is there a guru out there that can offer some advice?

RE: NX7.5 Expression or Function to Display absolute coordinates of Object

creating a point will create an expression for x, y and z.  Perhaps you could create an associative point and use the expressions.  You may have to wave link some geometry to associate the point since you indicated you are working on an assembly.

RE: NX7.5 Expression or Function to Display absolute coordinates of Object

like fgbrender mentioned , I use a associative point in the drawing file, where I rename the expressions to , for example , point_1_X , point_1_Y, point_1_Z, point_2_X , etc...

You can then reference these expression in a note or tabular note : <X0.3@point_1_X>

I have drawings were I use 20 or 30 coordinates like this.
The point are not associative to the model , but it is still easier then manually typing in the coordinates.
