Circular Arry (Is it possible to skip 2 or 3 arrays in UG NX-3)

[rock3x]

Is it possible to skip 2 or 3 arrays in UG NX-3.I know it is possible in NX-6 by Instance Geometry.I attached a part created with UG NX-6 with this.i want to know is it possible in UG NX-3.



Thanks In Advance.Please Help Me

In previous versions of NX, you could create the pattern shown in your part by arraying the extrude twice. Once using a positive value for the step angle and once using a negative value or by reversing the vector direction for the second array. This differs from your model in that the original extrusion would have to be united to the base part at creation rather than as a separate body as depicted in your example.

Alternatively, you can create a "full circle" array and suppress the instances you do not wish to appear in the final product.

I know this may sound like a stupid question, but why can't you just start your array with the Green feature and go in one direction rather than starting with the Red feature and then having to go in two direction?

I'd like to add some noggin fodder, which may/may not be applicable in this example, but is worthy of mentioning never the less (IMHO).... Prior to NX5, arraying spherical bearings, cylinders on a plate (sim to the previously submitted example), etc... And whether you grouped the feature and arrayed the group or not... once you define the array then the horizontal ref vector is permanently set. This is to say that it is NOT editable...

This issue went away with 'Instance Geometry' in NX5. There's another thread by me buried in here that has a bit more info...

CAD should pay for itself, shouldn't it?

Another option is to create the full array and then suppress the single instances you don't want. You may want to use suppress by expression so someone does not unsuppress it without extra effort.
