RIMITIVE
The Line primitive is a line drawn between two points. Its only properties are the
style of line to be used. In addition to the solid colors shown on the line toolbox, a
number of dotted styles can also be accessed via the properties dialog box.

The Rectangle primitive is a rectangle with a defined outline and fill pattern. The
fill pattern may be set to No Fill to draw the outline alone, or the outline may be
set to None to draw a figure without a border.
The Round Rectangle primitive is similar to the rectangle, but has rounded
corners. When the primitive is selected, an additional handle appears, allowing
the radius of the corners to be edited by dragging the handle from side to side.
The Shadow primitive is similar to the rectangle, but with either a drop-shadow,
or with a shaded 3D effect. The primitive is often drawn so as to allow it to act as
a frame around text primitives or other groups of elements.
The Wedge primitive is a right-angled triangle located within one quadrant of a
bounding rectangle. In addition to the outline and fill properties, the wedge has a
property to indicate which quadrant it should occupy.
The Ellipse primitive is an ellipse with a defined outline and fill pattern. The fill
pattern may be set to No Fill to draw the outline alone, or the outline may be set
to None to draw a figure without a border.
The Ellipse Quadrant primitive is one quadrant of an ellipse. In addition to the
outline and fill properties, the ellipse quadrant has a property to indicate which
quadrant it should occupy.
The Ellipse Half primitive is one half of an ellipse. In addition to the outline and
fill properties, the ellipse half has a property to indicate which of the four
possible halves (think about it!) will be drawn.
The properties for these primitives need little further explanation, other than to point out that
the quadrant or half rendered by the Wedge, Ellipse Quadrant or Ellipse Half primitives can
also be edited via the command found on the Transform menu.

The Conical Tank primitive is a conical tank with a defined outline and fill
pattern. When the primitive is selected, additional handles appear, allowing the
exact shape of the tank to be modified by dragging the handles as required.
The Round Bottomed Tank primitive is a tank with a defined outline and fill
pattern. When the primitive is selected, an additional handle appears, allowing the
exact shape of the tank to be modified by dragging the handle as required.
The properties for these primitives need little further explanation.
