Creates a Triangular Irregular Network (TIN) or MultiPolygon from items in a named list, using advanced creation properties. A TIN is a special type of surface item. If a Group is open, then graphics are added to the Group, otherwise a new Item is created.
A Named List containing items which will be used to create the TIN or MultiPolygon.
If the items are Points the x,y origin of the point will be used.
If the items are LineStrings or Polygons the vertices will be used.
- The expression to use to calculate the Z value of the positions being triangulated. Use "_oz#" for the Z height of the item.
- The Item class which this method will create. This may be "Area" for MultiPolygon items or "TinSurface" for a TIN.
- The number of triangular faces per Tin or MultiPolygon making up the surface.
