Symbolize a feature by number of geometry parts

Idea created by 1_rdklein on Apr 29, 2014
    In the course of routine editing, e.g. topology, it's quite easy to inadvertently have false geometry  parts added to features.  For example, a shard or tiny line segment might remain after trimming something, or you might get a donut hole, or a part inside a donut hole where these are not desired.

    While it would also help to have a parts-based topology rule, there are also times you might just want to see at a glance which features potentially have problems, without having to examine the 'Edit Sketch Properties' or try 'Explode Multipart Features' tool for every single record in your data.

    Why not be able to symbolize the number of parts to speed up a visual QC?
