Wave Geometry Link

Hi,
Is there an option to link Datum coordinate System of one part to datum coordinate system of another part directly. Like in catia, we can publish the axis system and use it in another part. Is the same possible in NX8.5

Hi,

What would the desired behavior be after you created such a link?

Hi Ronald,
I would explain the scenario. It might help u understand. I have two parts: Part 1 and Part 2.
In part 1, I have created all the sketches required for part 2. Basically it will be a skeleton for other parts. In part 1., there are two coordinate system. One at absolute position and other at an offset at 100mm. I have created all sketches with respect to the offset coordinate system. In part 2, I am linking all the sketches from Part 1 and creating the features.
So any changes in part 1 will result in changes in part 2. so if I change the offset value from 100 to 200mm in part 1, same has to take effect in part 2.
While assembling, the parts position will be as per part 1, even if I don't constrain. The sketches would perfectly overlap on each other.

Thanks,
Isha

This is just basic behavior. When you create the wavelink ,make sure the "position independent" option is deselected.
Now when you move the original geometry the linked one will follow...

yes, as Ronald says, This is the default behavior. You create the wave link , that's all.

but there is no option for wave linking coordinate system

 

[NutAce]

No, but you can select the datums and the point seperately

But in this case you do not need to wave link coordinate systems... if you have three parent/child levels, 1-sketch with offset coordinate system, 2-components that are taking sketch elements from level 1 by wave links to part 1, 3-assembly where you put your parts from level 2, then level 3 will move as you move coordinate system in 1 without need to wave link CSYS. this is good way to make a model without using constrains. it is called master sketch method.
