Am trying to add a second Geometry column to a feature class. I know Arc applications won't know about this field -- and I would not want them to -- but the field would be added to support custom functionality. The basic process of creating a field of Field Type Geometry and adding it to the feature class just fails. Have tried adding a blob field and storing a Geometry into it errors as well, though I haven't gone very far down this path.
I realize I could create another feature class with a relationship to the first, but want to avoid this if possible.
Any pointers on a preferred method that's been found to work would be much appreciated.
