Hi,

I created a workbench to convert an excel files records to point feature class and I need to create a polygon surrounding the point depend on a field in the attribute table, So I used the Hill Accumulator to do this but each time I choose a field in a the group by option I got an error as you can see below.

Please note that when I cleared the group by option the workbench is working fine and I got one polygon, so what did I miss in my workbench. Any Ideas to solve this?

Cheers,

Rawan

Hi @rawansaleh,

Apparently the result of the HullAccumulator produces other types of geometries expected by the feature class.

You can use a GeometryFilter after the HullAccumulator and view the results before trying to write.

If there is only one feature in your group by option, then this will remain as a point, it won't be replaced by a polygon, it will then cause an error when you try and write this point to a writer that only accepts areas.

Than you for your answer, yes that solve my problem

Thank you for your answer, so do you know how I could filter those points who have only one record the create a buffer on them?

I would use a geometry filter to get those features that remain as points after the hullaccumulator and then send them to a bufferer to convert to polygons
