Automation: Create or edit 3D polygons

In Surfer Beta you can now create and work with 3D objects including 3D polylines, 3D polygons, and 3D polymesh! This functionality has also been added to automation. See below for specifications on how to use the new objects and methods in automation:

The AddPolygon3D method was added to the SrfShapeType enumerations.

Method	Description
AddPolygon3D	Adds a new simple 3D polygon shape.

AddPolygon3D()

Parameter	Type	Required/Optional	Default	Description
VerticesXY	Array of doubles	Required	N/A	The X and Y coordinates (first entry is X coordinate of first vertex, second entry is Y coordinate of first vertex, third entry is X coordinate of second vertex. etc.) for the new 3D polygon.
VerticesZ	Array of doubles	Required	N/A	The Z coordinates for the new 3D polygon.

Syntax

Set Polygon3D = object.AddPolygon3D(VerticesXY, VerticesZ)

Remarks

Returns an IPolygon3D object.

Example

This example demonstrates how to add a 3D polygon to a plot document.

Sub Main
    Set surf = GetObject(,"Surfer.Application")
    
    Set plotdoc1 = surf.Documents.Add(srfDocPlot)
    Set shapes1 = plotdoc1.Shapes
    
    Dim polygon3dcoordsXY(7) As Double
    polygon3dcoordsXY(0) = 1 : polygon3dcoordsXY(1) = 2
    polygon3dcoordsXY(2) = 2 : polygon3dcoordsXY(3) = 2.5
    polygon3dcoordsXY(4) = 3 : polygon3dcoordsXY(5) = 2.0
    polygon3dcoordsXY(6) = 4 : polygon3dcoordsXY(7) = 2.5
    
    Dim polygon3dcoordsZ(3) As Double
    polygon3dcoordsZ(0) = 1 : polygon3dcoordsZ(1) = 2
    polygon3dcoordsZ(2) = 3 : polygon3dcoordsZ(3) =4
    
     Set polygon3d = shapes1.AddPolygon3D(polygon3dcoordsXY, polygon3dcoordsZ)

     'use the 3D polygon object from here on
End Sub
