Attaching a GD&T Symbol, NX3
Attaching a GD&T Symbol, NX3
(OP)
Does anyone know a way to attach a GD&T feature to a side view of a cylinder? The top and bottom of this cylinder needs a flatness and a parallelism spec, but in order to attach to it, I need to create a line. Otherwise I cannot grab anything to attach too.
I have linked a sample image, any ideas? I've looked in the quick pick tab, but nothing can be selected.

I tried to use Simplify Curve to "explode" either end of the cylinder and that completely removed the center portion of the ends. Can you attach the GD&T leader to the dimension's extension line instead? How about making a section cut of the cylinder instead of a viewport?

To attach a GD&T callout to an existing dimension extension line, type your text in Annotation Editor then on the Annotation Placement toolbar, select either of the last 2 pulldown icons on the far left (leader type?). Next select the Leader Tool icon to bring up the Create Leader dialog. Next, select the Leader Type pulldown and pick the 3rd icon from the bottom on the list. Select an existing dimension line then drag to place the callout.
That may not be what you're looking for, but that may be an alternative.

Ok, from there, is that the correct way GD&T should be placed, or should be off an extension line, like the flatness and parallel callouts, are?
I am assuming NX will limit me to what is acceptable in the GD&T world and not let me create something that is no longer standard.

Regardless of what the leader "head" (either a triangle or just an extension line) looks like, it means the same thing as far as I know.

1. Create another horizontal dimension, as if you were adding another length dimension.
2. Edit the dimension by right-clicking on it.
3. Change placement to arrows out and drag the number in the dimension to either left or right of one of the flat faces.
4. Right-click again and choose style, then the dimensions tab. Depending on how you selected the edges, click the leader and arrow at one side under the tab headings. Then click apply. The dimension you just created will now lose a leader line and an arrow.
5. Now the naughty bit. From the top menu, select edit > text and then click the dimension (in your case 62). You can now edit this by clicking on the 'A' just above the box.
Select the GDT Symbols box. Delete the 62. Click OK whenb the warning box comes up and enter the desired geometric tolerance. When complete, click close.
You can now drag the tolerance to where you need it.
Repeat the process for the other tolerances you require.
Note that you may need to fiddle with the dimension's style preferences go get it just right.
This may sound very involved but once you've got the hang of it, it's quite easy to do and edit. Beware that it will flag up as a manually edited dimension if you use that particular check.
Hope this helps.
Fred.

I tend to find this method more flexible and posted it as a useful alternative. You still have to make sure that it complies with whatever drawing standards you're using, of course. I wanted to post an image of the result that I get, but haven't got an accessible website.

Easy to use, and I've had good luck with them.
