Abstract
A dome shaped structure, and the method of constructing it, are described using curved gore-shaped construction panels which have grooves in their side edges. Rectangular tubular joining members are placed in the grooves, secured therein, and serve to join adjacent panels together. This provides a level surface where the panels are joined so that such adjacent edges of joined panels are even making the interior surface suitable for use as a projection surface.
