Assume you can get that element, that is a builtinparameter:

> **[BuiltInParameter Enumeration](https://www.revitapidocs.com/2022/fb011c91-be7e-f737-28c7-3f1e1917a0e0.htm)**
>
> Online Documentation for Autodesk's Revit API: 2015, 2016, 2017, 2017.1, 2018

Divisions have a builtincategory, so an element collector could get them, but they might not have much in the way of class/API beyond that based on my searching:

I tried to use RIR to implement this feature, but it prompted me that “Parameter ‘Gap’ is not defined on ‘Element’”. I found the API named PARTMAKER\_PARAM\_DIVISION\_GAP, but I’m not sure if it can be implemented using C#.

It looks like the element is divisions as oppose to the geometric element. Try collecting all elements of that category instead and inspect its parameters to see if there’s a way to get it back to its relater elements.
