Description

The Shape, a 2D polygon object, represents the input geometry to be added.

The Type indicates how the resulting edges of the embedded polygon will be coded. Supported edge types are esriTinHardEdge, esriTinRegularEdge, and esriTinSoftEdge.

The TagValue is a signed, non-zero, long integer that will be assigned to the triangles inside the embedded polygon.

The edgeTagValue is a signed long integer that will be assigned to the embedded polygon edges. A zero can be used to ignore edge tag value assignment.

The NodeTagValue is a signed long integer that will be assigned to the embedded polygon nodes. A zero can be used to ignore node tag value assignment.

The Seed is a TinTriangle pointer. If you're interested in obtaining a seed that can be used as a handle to the added polygon then have the seed point to a TinTriangle object. The object will then be populated with the appropriate properties. If you're not interested in obtaining a seed then pass a NULL pointer ('Nothing' in VisualBasic).

The optional Z can be used to define a constant height to be used for the added polygon. If unspecified, heights will be interpolated off the existing surface.
