Drawing elliptical and circular arcs
To draw an arc, choose the appropriate Arc symbol in the Circles
and Ovals toolbar. Drag with the mouse to create a guide circle or
ellipse.
Release the mouse button and move the cursor to the position where
you want the arc to start. In the status bar, you can measure the
actual angle in degrees. Single-click this point; the circle (or ellipse)
disappears and moving the mouse creates the arc. Again, the status
bar shows the current angle.
When you have drawn the arc to the length you want, click once
more. The drawing of the arc is complete.
Curves
The tools for drawing curves or polygons are on the toolbar that appears when you
click the Curve icon on the Drawing toolbar. This toolbar contains eight tools
(Figure 27).
Note
Hovering the mouse pointer over this icon gives a tooltip of Curve. If you
convert the icon to a floating toolbar, however, the title is Lines, as
shown in Figure 27.

If you move the mouse cursor over one of the icons, a tooltip pops up with a
description of the function. For a more detailed description of the handling of Bézier
curves (curves and filled curves), see Chapter 10 (Advanced Draw Techniques).
• Polygons: Draw the first line from the start point with the left mouse button
held down. As soon as you release the mouse button, a first corner point is
drawn; move the mouse to see how subsequent lines will look. Every mouse
click sets another corner point. A double-click ends the drawing. A filled
polygon automatically joins the last point to the first point to close off the
figure and fills it with the current standard fill color. A polygon without filling
will not be closed at the end of the drawing.
• Polygon 45
0
: Like ordinary polygons, these are formed from lines but with
angles of only 45 or 90 degrees between them.
