Description

SetSelection selects all elements returned by the passed enumerator.

SetSelection will run through the passed enumerator, leaving the enumerator at the end. To subsequently use the enumerator for something else you must first use IEnumTinElement.Reset otherwise it returns a Null pointer ('Nothing' in VB) for Next and an empty element for QueryNext.

When working with edge selection the software will ensure an edge selected/unselected in one triangle will also select/unselect the corresponding edge in the neighboring triangle. So while there are technically two edges separating adjacent triangles TIN selection handles them logically as one.
