WAVE linked geometry in NX 8.5

[aleksandar81]

I'm trying to create interpart link geometry inside the sketch (component 2 ) to create associative constraints that references the perpendicular edges of the component 1 in the Assembly.I have 3 questions.

1.If I create fillet in a sketch on component 1 , that change will not reflect on solid body component 2 with linked geometry, instead it will turn into sheet because it can't adopt change.How can I make linked associative constraints that will reflect that change?

2.In assembly if I move component 1 , component 2 is bonded with component 1, I can't separate them.

3.Is 'it possible to make wave linked geometry that will reflect changes made with synchronous modeling on a parent component.

Directly creating Wave Links while INSIDE the Sketcher is not supported until NX 10.0. In NX 8.5 you'll need to created the Wave Links objects (i.e. curves) before you create your sketch and then import them into the Sketch if you wish for them to be part of the Sketch profile.

I saw your NX10 quick tip for direct wave link inside sketcher,Great stuff.
When I wave link on parent component edge and project on child component in sketcher that same edge,I can't select that edge to constrain it with colinear relationship the way you did.

I guess associative constraints in questions 1 and 2 are not feasible.

 

[JohnRBaker]

The behavior of so-called 'recipe' curves, of which projected and WAVE-Linked curves are included, has changed somewhat starting with NX 10.0. Perhaps this is why what you saw was closer to what you would like to do but can't at the moment.

Thank you John ,how can I create a WAVE-linked sketch,I cant selects sketch along the edge of the parent?

Check your selection intent...

Selection intent is fine,that's not the problem.

Is the sketch 'external' to the body that is was used to create? There is also the 'Timestamp' issue. The WAVE-Linked curves have to have been created BEFORE the Sketch was that you're now attempting to import the curves into.

Yes.

OK, I know that, but looks like something is slipping under my radar. If someone can send me an example with WAVE-linked sketch I would really appreciate that.

 

[NutAce]

Mayb it is easier when you send an example of your sketch..

NX can't WAVE-Link a sketch, only curves that are part of a sketch. You can only WAVE-Link geometry. A sketch is a Feature that is made up of geometry.

OK, this is for NX 10,but it's the same for NX 8.5

In steps 3 and 4,you select Sketch as WAVE Link Type,and then
select the sketch along the top edge of the parent part cutout.When I try to do the same thing nothing is selectable.This is a type of example I'm looking for,and how to use sketch as WAVE Link Type.Now I'm little confused because of John's comment.

 

[JohnRBaker]

I'm sorry, I think I've confused you all as I had a bit of a 'brain fade' there

Yes, Sketch features are legitimate object types for WAVE-Linking.

That being said, without actually seeing the part/assembly or at least a video showing what it is that you're attempting to do, I'm not sure that anyone will be able to help you all that much.

I would just like to learn how to use this option -sketch as WAVE link type. I don't have any special assembly to show you, my question comes from experimenting with simple two component sketch+extrude shapes in an assembly, that being said as I already have mentioned, if someone has an example of using this option, I would like to see it please.

 

[JohnRBaker]

What EXACTLY are you trying to do? Are you trying to WAVE-link a sketch from one Component into another Component, so as to drive (i.e. control the size/shape) some feature in that second Component by editing the sketch in the first Component?

[aleksandar81]

Yes John,that's what I would like to do.If you take a look my first question,then you will see what type of control I would like to try with sketch as WAVE link type.

 

[JohnRBaker]

You know it would help immensely if you would simply provide us with a sample Assembly file, or at least a picture of what it is that you're attempting to model.

OK, here's what I was saying in pictures.

I first made sketch+extrude for the first component, and then WAVE linked face edges to be associative and position independent in the second component. After that, I made sketch using 2 edges as projected from the first component, trimmed it, and then extrude it.

So far everything is routine. But now if I cut the step in left corner of the first component, that change will not reflect on child component, it will "loose" that information and turn in to a sheet.

My idea was, is this possible to avoid by using a sketch as WAVE link type, and in general how to use sketches as WAVE link type, because as I already said I can't select anything when I try.

 

[JohnRBaker]

If that's the sort of thing that you want to do, I wouldn't even mess with WAVE-linking the sketch. I would WAVE-link the entire body, as I did in the attached example. Just make Comp_1 the work part and un-suppress the last feature and see how it updates, just as you want it to.
