Locating a helix in part (NX7.5)
Locating a helix in part (NX7.5)
(OP)
The problem is how to constrain a helix (or Spring) location? (in 3d) relative to the "hole" center...
Looks once the helix is moved by draging, no way to locate it any more...
This is not for assembly but producing aq part of multiple parts.
Thanks for your time

For more complex parts, it may be advantageous to create a dedicated 'constraints' reference set that contains datums to use when constraining to other parts in the assembly.

The Spring and the another part (base with a hole) are inside one single part file (parts can be substracted, unite, ...).
The Spring is away from the hole (moved). I have to move the Spring so its cebterline is at the hole centerline (please do not ask why this all... it just has to go that way). I can make a new Spring with a small cylinder (or 3d-line) in the middle, but moving a cylinder does not moves the Spring...
If i make a datum axis as a Spring centerline, can i move the datum axis so and Spring moves, ALL WITHIN A PART FILE ONLY.

An alternative is to use the swept command instead of the helix. Create two lines perpendicular to each other (the result will be an L shape). One line will be the axis of the helix (controlling the length), the other will represent the radius of the helix. Use the swept command with the angular law option to create a helical sheet body. The outer edge of the body can now be used as your helix and its position will be controlled by the input lines.

See attached. Tray changing the parameters of the chamfer, the spring pocket and spring will follow (within limits).

hard to beleive we will update to NX8.
Datum axis does not works at the moment so well (cannot insert dimensions from it to the coordinate system, or anywhre else...)
will tri 2 point and 3d line as a centerline, group it all and change coordinats of the points...

The one of work around solution for that issue can be creating helix shape with “Low Curve” feature.
I have created expressions and using it made “low curve” (helix curve) which is associated to hole axis. Whenever you change location of hole - helix geometry will follow accordingly.
Please see attached.
