Hello everyone! 😀 I did a search in [revitapidocs.com](http://revitapidocs.com) and I did not find that method that I saw in other posts, I even tried it in my Python Code, and if it works. But where did it come from? In [revitapidocs.com](http://revitapidocs.com) I only found GetBoundingBox(), what’s the difference with it? ---

I believe certain get/set parameters can be written that way, but there’s no difference as far as I’ve seen. ---

I think it is one of these old, old things that just still works. That would be a very Autodesk thing to do. Note that is show in the API examples under Element \> BoubingBox. From 2008: [The Building Coder: Element Bounding Box (typepad.com)](https://thebuildingcoder.typepad.com/blog/2008/10/element-bounding-box.html) ---

Hi Nick! I found this: ![imagen](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/1/01d58979c740115b7b52a56f9cc597a444986de8.png) Thanks to the link provided by @aaronrumple, and that documentation belongs to Revit API2009, from what I try to understand, those methods are still used, right? ---

Overload properties used as methods. That kind of makes sense. Thanks for the info. ---

Not sure why its not listed in RevitAPI docs, but its definitely there if you browse the Revit API in say Visual Studio: Property overloading isn’t supported in C# so you have to use the method as the property can’t be used. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/1/2183a5a604baaccc4217e8afc834306d61cfc1e0.png) ---

Hi Thomas! Wow, I can see the get\_BoundingBox method there!, how do I get that API documentation?. I have Visual Studio Code and it doesn’t appear in the autocompletion. ![imagen](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/9/d9e137f94724f4fcb96c5fe9c0ab4edeab0f7c80.png) ---

In the fine print. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/f/cfbcbfd812ea63ba0d883b3cf02dea981c3a0a73.png) Note that the vb examples uses .BoundingBox, but C# uses .get\_BoundingBox() ---

Very similar question was recently asked on the API forums. It is a C# thing, not a Revit thing. > **[Whats the deal with get\_Parameter()? (insert Seinfeld Bassline here)](https://forums.autodesk.com/t5/revit-api-forum/whats-the-deal-with-get-parameter-insert-seinfeld-bassline-here/m-p/11847065/highlight/true#M70174)** > > This is more of a request for a history lesson here about the Revit api, but whats the deal with the method get\_Parameter()? I've seen it used in past forum posts for use in Revit versions before 2022, but I don't see any references to it...
