How do you handle wave bodies an threads

How do you handle wave bodies an threads

How do you handle wave bodies an threads

(OP)
Started working with wave link bodies you don't think about threads in your geometrie used in an other part. Because you expect that simplfied threads working across wave geometrie but they don't. How you use threads and wave links?
Is there a common workaround?
How do I create a detailed thread with new hole - NX5?

RE: How do you handle wave bodies an threads

With the new hole the threaded hole type is available by selection from a pull down list near the top of the dialog window. That's the easy bit out of the way.

Now linked bodies do just that they create a linked version of the body. They don't and have never carried the threads with them in the same way as they are existent in the original. However when you think about it all that is missing is a couple of curves and the property of the  parametric thread which allows that it will appear with the correct drawn representation on drawings. If you add threads to the existing holes then in the first instance they will generally assume the correct result, by guessing it from the ID.

On the other hand when planning to use linked geometry it is probably preferable that you apply threads after the linking takes place and maintain them after the fact as a matter of policy since a scenario exists that will cause incorrect results. Should you for example assign a certain sized thread to a hole prior to linking that body and then reassign the correct thread to the linked body then things will appear to be correct. But should you later change the thread in the parent part do not assume that the thread applied after the link in the part containing the linked body will be changed. In the normal course of events it will remain the same until you change it, as it really only uses the hole in a linked body as a place holder for the thread.

I hope this makes sense to you and avoids any problems that could be foreseen.

Ok you have use the new hole, the problem is for manufactoring reasons we want to use the wave link body in another part ...
 

RE: How do you handle wave bodies an threads

You can use the older hole and then add a thread feature, or you can use the new hole and the threaded hole type. Either way you'll get more or less the same geometry when wave linked but without the dashed font curves indicating which holes are threaded and which might just be plain holes.

Now a plain hole that is parametric will allow the thread definition to vary the hole size, otherwise you'll get "Cylindrical face diameter is in conflict with thread definition" in most cases but the thread will still be applied.
