Hi mdesign,

There is a built in function for it in v4 currently, under the detailed object properties dialog.

It gives a report in there on the number of joined and naked edges in an object and all of the labels in the report are clickable, if you click on any of them it will select the corresponding objects.



In v5 there will be another way to do it as well using the Scene Browser. There will be various sub types like you'll be able to go under Edges and use the entry for Naked edges to target them.
