I would like to list all the relations of a active sketch in a listbox and delete selected ones.

I can get a list of relations that are exposed through SldWorks.Sketch.RelationManager.GetRelations(swAll)

the only usefull thing exposed in the ISketchRelation Interface is "GetRelationType".

I need more to be able to select the relation with : ModelDocExtension.SelectbyID2

So can I select a Relation with "ModelDocExtension.SelectbyID2" ?
