Select XYZ Point Data

The Select XYZ Point Data dialog is used to select point data for interpolation from a point source object. The dialog shows the available values in the object. Point elevation is always available and is simply the elevation (Z) of the point.

The values: color, scale X, scale Y, and scale Z are available if a value (field) in the dataset used in the source object is used to scale one of these properties. In other words a field from a dataset must be used for symbology in the object to be available for interpolation.

2D Grids
When interpolating 2D Grids you most often use point elevation as the interpolated value although it is possible to interpolated any of the available values. X and Y coordinates are retrieves automatically.

3D Grids
When interpolating 3D Grids you should not use point elevation as the interpolated value. The interpolated value should be a value that varies in all directions in 3D space. X, Y, and Z coordinates are retrieved automatically.
