To first step in creating a polygon is defining its center. The point
position can be defined either by clicking or by entering the exact
coordinates in the property window. In the same window, one can
specify the number of sides and the type of the polygon (inscribed or
circumscribed). Next, define the radius and the rotation angle of the
polygon. To do this, either define a point by clicking , to become a
polygon vertex, if inscribed, or a midpoint of a side, if circumscribed, or
else explicitly enter the radius and the polygon rotation angle in the
property window.
Creating Ellipses and Elliptical Arcs
This option, just like previous ones, has a pull down list of icons for
creating an ellipse or elliptical arc.
Elliptical arc
To create an elliptical arc, use the option:
Graphic Elliptical Arc
After calling the option, define four points: the center of the ellipse, the start point of the arc, the end point of
the arc and an additional point in the elliptical arc defining its position. The point positions can be freely
defined by clicking , or entered exactly in the property window.
After defining the center and endpoints, an elliptical arc will start rubberbanding on
the screen following the pointer. The pointer defines position of the additional point
in the arc. If the rubberbanding arc disappears, that means, the arc cannot be created
at this pointer position. The point coordinates can also be entered in the property
window. In a special pane provided in the window, a relevant warning message is
displayed upon an attempt to enter inadmissible point coordinates.
