Attribute rule to create polygon feature from line features.

Question

Hello,

I am hoping someone might be able to help me with writing an attribute rule that will generate polygons in a feature class triggered by the creation of lines that form closed areas in another feature class.

I imagine this rule would work by looking at whether the line created closes a shape (based on some topology) and if 'yes' then a polygon is created if 'no' then a polygon is not created.

This rule would be a huge help for those of us creating maps that would like to see what our maps are looking like in real time rather than having to run the features to polygons tool over and over.

There would need to be some other attributes for the polygons, but I thought I'd start with generating a polygon first.

Thanks so much for any help you might provide.

Hey Hlynur,

this scenario is described in this blog: https://www.esri.com/arcgis-blog/products/arcgis-pro/data-management/advanced-gdb-attribute-rules-editing-external-features-with-attribute-rules/

Hey @JohannesLindner and thanks for a great solution.

I have a similar problem, being that I need polygons to be created automatically in one feature when a point is created in another one, the polygons being a buffer for the point set to a default radius.

So to sum up, a point is created in a feature and automatically a polygon (buffer) is added in another polygon feature (with the respective point being the polygon/buffer center).

Any tips on how such a attribute rule might look like?

With regards, Hlynur.
