Provide API to create Extend Feature

[CattabianiI]

Please provide as other part features the ability to create the extend feature: something like AddByEdges or Add(ExtendDefinition).

Don't know why this has not yet been implemented.

One of the funny things about this is that the ExtendFeatures API collection object was exposed to us all the way back in Inventor version 11, which was created back in 2006, according to the online help documentation for it.  But in other areas of the same online help documentation, it tells us that we can use this to create new ExtendFeature objects, which of course we can not...hence the need for this Inventor Idea post.  That faulty documentation can be seen from the PartFeatures API help page, when you scroll down to its property for accessing the ExtendFeatures.

😂

And also, when you click on that PartFeatures.ExtendFeatures property, to see the help documentation about it, it says the same thing.

🤣

But when you then click on the ExtendFeatures link provided on that page, which takes you to a help page for that ExtendFeatures Object Type, it mentions nothing about having the ability to create/add new ones in its main description, and does not show ANY methods that could be used to create/add a new one.

🤔🙄

It may be funny for a minute or two, then it just sucks. 😠

I even blamed myself for using 2024 documentation on Inventor 2023 after reading that line and not finding any creation method.
