I am using Creo Parametric Release 6.0 and Datecode220.127.116.11
There appear to be a collection of points in a sheet metal part related to the Driving Surface feature. It's unclear how they were created. They are un-selectable, and I am unable to remove them from the model.
I don't know why but when I deleted the driving surface (and all the features after) and recreated the driving surface the points didn't come back.
