Introduction

The purpose of this command is to merge selected surfaces into one surface.

The Merge Surfaces Menu

The content of the menu

Select the surfaces to be merged by transfering the chart names into Selected Chart Name.

Default name for the chart containing the merged surfaces is mergedChart.
That name will be used if the field for the new chart name is blank.

A new chart name can be entered that will be used to save the merged surface in the same chart folder.
In either case the size of the merge surfaces will be the min and max values for the set of input surfaces.

If the task is to merge surfaces within a new chart frame, create first that chart and browse it in.
The algorithm will then use the definition of the browsed chart as the grid frame for the merged surfaces.

Priority when overlapping surfaces: The sequence of the selected surfaces determines the priority.

The grid increment for the merged surface can be selected from the first grid or specified explicitely.
The x and y grid increment will be equal.
