You can retrieve the coordinates of the Aerial view camera in the Home.xml file of a SH3D file. As a SH3D file is actually a ZIP file, open it with any zip tool, the view the Home.xml file it contains and look for the line starting by [font=courier new]<camera attribute='topCamera'[/font] where you'll get the values of [font=courier new]x[/font], [font=courier new]y[/font], [font=courier new]z[/font] (=elevation), [font=courier new]yaw[/font] (=body angle), [font=courier new]pitch[/font] (=head angle) and [font=courier new]fieldOfView[/font] attributes. Then, copy these values in the Virtual visit modification box (angles should be converted from radians to degrees).

[Edit: it looks like you found the solution by yourself [;)]]
