Dear All,

Issue. Wrong sline description
I've found in sline description the following text: A spherical line is part of a great circle (meridian) that has a beginning and an end and hence, a direction. I guess it is a wrong statement. The line like sline( spoint '(0d, 10d)', spoint '(10d, 10d)' ) is not a part of a great circle (?) but it is a valid sline. Great circle is defined as the cut of the sphere by a plane containing the sphere center. What do you think?
