The right side vertical points in Dome are stored in PlistA
The left side vertical points in Dome are stored in PlistB
In the special case where the revolution angle is 180°, all points are stored in PlistA and the
number of vertical subdivisions is stored in ONVert.

Hint! The dome can be made elliptical, using the MScale statement.
The Dome2 statement
The Dome2 statement is a Dome shell of the calotte type, where the
vertical revolution angle is not necessary 90°. Rather then
specifying the dome by a revolution angle, it is specified by the
width and height. Dome2 may typically be used for modelling
dome shaped ceilings.

The syntax for Dome2 is:
Dome2
A unique number from 1 to 2.147.483647 for identification of the first point and surface in the
Cone. Using the same number, but with negative sign defines the surface and its mirrored
counterpart in the XZ-pane (Y = 0). A Cone will take up several point- and surface numbers,
which must all be unique.
Specifies the number of surfaces in one horizontal ring of the dome, around 16 to 24 surfaces
per ring is suggested. ODEON will automatically calculate the number of subdivisions in the
vertical level. If the revolution angle is 180° the number is stored in the ONVert variable would
have been 9 in the example above. The ONVert variable may help when connecting a Dome2 to a
Cylinder2 in order to specify the correct number of surfaces in the cylinder.
Width at the beginning of the dome. The width must always be greater than zero.
The Height must be different from zero. If the height is less than zero, the orientation of the
dome is inverted. Height must be different from zero and less or equal to ½*Width.
Revangle must be within the range +/-360° and different from zero. If RevAngle is 180°, a
half-cone is generated, if its 360° a full cone is generated. Positive revolution angles are
defined counter clockwise.
