UG NX 6.0 associative spiral
UG NX 6.0 associative spiral
(OP)
Hello,
I'm trying to create a snail cam within NX6. I can easily create one using the helix tool with a 0mm pitch and then use a law curve to get the start and end radius. Nice and simple!
The helix tool cannot be associated to planes/points so when the assembly or sketch moves the helix gets left behind and everything falls off. Does anyone know of a method to get this simple snail cam profile in an associative method. I have tried using splines with multiple points which kind of works but it does not produce a perfect linear profile and again it falls off if the profile is changed.
Kind regards,
Adam

As far as my knowledge is concerned ...Helix dialog changed NX7/7.5 onwards (with respect to it's associativity in terms of origin and direction)
As a raw workaround (for NX6) what you can do is :
(1) Create one Datum CSYS (at the desired location and with desired vector directions)
(2) Then using Instance geometry copy the original helix to this location (using Co-ordinate System to Co-ordinate System)
Now for use...use this copied feature.I know this creates a dupliacte copy but i am not aware of any other method in NX6.

I never thought to do that. Well done, it's perfect. Even I don't need this method anymore in NX8.5
