Feature Vertices to Points - Start and End points of a polygon are always two duplicate points?

[MattBell1]

Whenever I run a polygon through the "Feature Vertices to Points" tool I choose "All Points" and always get duplicate points at the start of each polygon, one point for "Start" and one point for "End" stacked on top of each other. This doesn't make sense to me because when making a polygon, you get close to the start point but normally you don't double-click on the start point to end the polygon. Does ArcPro always consider the start and end points of a polygon the same point? 

So, the reality is that, for polygons run through this tool, there's no way to not create duplicate points at the "Start" and "End"? We always have to go back in and manually delete one of the duplicate points? Can we make a "Point Type" setting option to eliminate duplicate vertices?

Polygons in esri geometry will have an equal first and last point, hence a triangle requires 4 points to define its border with the first and last point being equal, and you can't omit either

Thanks, I was afraid this was how it worked. I just wish there was an option in the tool to eliminate one or the other since they're duplicate/redundant and are only a single vertex point, where the trajectory of the line changes, in the polygon.

I want to create a vertices layer consisting of tens of thousands of vertices for a web map (so manually editing out the duplicate isn't an option) and don't want to confuse people in mobile apps when they tap on one point and see two in the list. It also unnecessarily makes the feature layer larger. 

I guess I just don't understand why the ESRI rules of polygons need to also apply to defining geometric vertices, since the geometric definition of vertices doesn't include the beginning or end of a square, for example. There are only four (4) vertices in a square, but ESRI's Feature to Vertices tool gives me five (5). I now understand why but wish there was an option to disassociate the duplicate to result in just the simple geometric vertices.

Running this tool after you convert to vertices might do the trick:

Thank you! As annoying as it can be to run tools after tools to achieve something I think the original tool should have a setting for, this will get the job done at light speed relative to manual editing. It’s a solution. Much appreciated!
