Why wave geometry is created? 2

[pratyu]

General Question:-

Apart from the fact that operation (hole,extrude, etc) can be done only on solid wave body and not on the actual solid component (the parent of the wave body); is there any other reason why wave geometry is being used?

Apart from the fact that operation (hole,extrude, etc) can be done only on solid wave body and not on the actual solid...

I think we need to establish some facts first...

If you make the component part your work and/or displayed part, you can perform any operation you want on the actual body. Wave links are most often used to help create similar parts (e.g. left hand/right hand parts) or parts to represent secondary operations (e.g. part as cast/part as machined). There are other uses as well, but I can't think of a situation where NX forces you to use wave linked solids rather than the original part.

In what situation are you forced to use the wave linked body?

I use wave whenever I need to create multiple parts from one basic source shape. For example if you design computer mouse - you want to have single solid shape source file (not shelled). Than you create all components - top half, bottom half, buttons by wave linking geometry from source. You can trim what you don’t need with some parting surfaces, then shell the parts, put ribs and snaps etc. in each as needed.
Later if you need to change shape (or if you need new similar mouse) you modify the source geometry and all components update accordingly. Sometimes some features of the components need to be updated manually but this workflow if way more flexible than modifications to all components independently and hoping that put together they would form smooth shape.

Wave Linked Geometry is used for assembly processes. For example, if you have to components you want to assemble and in the assembly state, you want to drill a hole in both components. So, you can add the two components in an assembly, Wave Link those two components and then add holes in both Wave Linked bodies. Then, you can create an assembly drawing with your components having the holes in them. But, yet, the components you brought in the assembly will still have none of these holes.

Wave Link Geometry basically gives the ability to add features to the assembly that should not be in the component file. Manufacturing Engineers use Wave Link Geometry to help their work on finished components.

Also, some companies do not like 2D drawings in the same file as the model, so they put the Wave Linked Geometry in the 2D drawing file and draft from there. This is good for concurrent or parallel work, you have the designer working on the model at the same time the drafter can do rough drafting at the same time.

So, Wave Linked Geometry can be used for multiple purposes.

Note that the so-called 'Master Model' approach, where the Drawing is in a separate part file from the actual detailed model, does NOT depend on the use of WAVE linked models, but rather just the creation of a simple single-level assembly where the detail part is a component in the file where the Drawing is subsequently created.
