To bad that touch constraint is not a real touch
To bad that touch constraint is not a real touch
(OP)
Hi
How its to bad that touch constraint is not a real touch
and is also an imaginary touch.
because if it was only a real touch we cood do limited rotation to some angle
as seen in these pictures.

Post parts if possible, please - makes it easier to see what you've actually done when you don't take us through each step.

Thank you Xwheelguy
I mean a rotation of a range angle say from 0deg to 30deg not a fix angle.
I also post the example parts

That's good and far because my company
recently upgraded to nx8.5 and from history
I'll should wait two years for that.
RE: To bad that touch constraint is not a real touch
But NX8.5? Really? Support was ended last year for that version or do you not pay maintenance?

Thank you Petulf
this is good trick
I'll try it
RE: To bad that touch constraint is not a real touch
Your work around work very good.
But I need to move the handle to the rotation axis before moving the free link
if the handle is not on the rotation axis the free link refuse to move.
Do you experienced this.

- smart move there to use the Join Curves to convert the Arc to a spline , i would not have thought of that option.
( otherwise i am kind of "allergic" to the Join Curves, I see it used ( ex Catia people ?) as a selection method, which isn't that good since it will create an approximation spline on top of the original objects rather than a "selection group".)
It seems that it doesn't need the sharp corners shown by Petulf. If I edit the Join Curves and remove the lines , it works the same.
Anyway, a little trick to avoid the handles of the Move Component.
( - If I pick the "ball" on the arc I can rotate freely, i do not need to move the handle.)
Start the Assembly constraints dialog instead of the Move Component. Then place the cursor anywhere on the component to move, press and drag. It will move within its possible limits.

As for join curves I mostly use it for these sort of occasions IE when constraining something(sketch/asm) to a curve and there is no selection rule available.
RE: To bad that touch constraint is not a real touch
I have seen quite a few videos from "NX specialists" where they use Join Curves before creating surfaces.
- probably because some other cad system "prefers" to have a single object per section in the surface definition.
I am afraid that one then risks two times approximation, first the curves are approximated into a single spline. ( with G0, G1 continuity etc)
then that spline is approximated again when used in the surface.
If NX is smart enough it reads the original curves , but i don't know how to check that.

Thank you petulf
Thank you Tomas
On the new helpful info.
RE: To bad that touch constraint is not a real touch
I removed the corners lines (arc spline only)
and start the Assembly constraints dialog instead of the Move Component
and the drag works smoothly.
Thank you Tomas for these tips.
