Hi,
I was wondering what is the difference between using Promotions and Wave linking for interpart modeling? Also the benifits one way or the other. We currently use Wave linking for all of our interpart modeling. Thanks in advance!!
I used wave linking for taking geometry to another part that will influence the part.
I used promotions for adding features to an existing body in the assembly.
"Wildfires are dangerous, hard to control, and economically catastrophic."
We use linking mostly to mantain a link to customer geo. such as a core stick or casting file. Mainly because of the amount of eng. changes, which makes updating the coreboxes and patterns more automated.
Essentially Promotions are not much different then Geometry Links, Actually you can convert Promotions to Geometry links. With saying that Promotions should not be used, but instead use Link Geometry. I would be even inclined to convert all promotions to Geometry links. There is a setting to automatically do this, That sounds dangerous. I would like to force the change myself, just in case it goes wrong.
WAVE is not the same as Geometry links. Even though they appear to allow the same type of linking. They are more like cousins. Geometry links require an assembly or can link geometry within the part. WAVE is primarily used to create a high level dependency and share and build knowledge (datums, general geometry, expressions, rules. Some software packages call this a skeleton. This is not to be shared outside of the company. Then push it over the fence and have a component that is then added to an assembly. WAVE can link to files without requiring an assembly. Now you build your component using that linked geometry.
WAVE can be used to create a customer NX file without giving them the product knowledge, Keeping the internal faces on the body the same, easily updated, They won't see any assembly structure so no errors, the file can contain one or many solids, the solid can be simplified and then WAVE linked.
There should not be any need to remove parameters on any solid. Using WAVE will create an object in another file, there is not any other information in the file that a customer or supplier can extract, especialy if you simplify the model first sort of like a black box.
