2. Draw the first control line (defines starting point) – it will NOT be visible, but it’s
position and angle defines the left part of the line
3. Draw the second control line (defines end point) – this one will be visible now,
as well as the first control line. Plus the drawn line becomes visible as well.
4. A dialog opens asking if a blanked end point should be set. Choose “yes” in
case there should be a blank between the Bezier’s end point and the next
line/point. Select “no” if the next line/point should continue the line after the
last Bezier point.
Important: It is very important to understand the 4
coordinates of the two control lines, as there are
more ways of using Bezier curves. To change those
options, right click on the icon. The dialog shown in
Fig. 38 opens.
Different settings, like the Bezier type, the point rate
or point density can be specified.
Bezier Type:
The 3-point-Bezier is a special form of Bezier, where
the two control lines have one point in common. This
slightly changes the drawing procedure described
previously.
Please try the tool out to get to know this special behaviour of the Bezier tool.
Point Distance:
The point distance defines the number of points drawn to create the curve. The
difference between “density of points” and “number of points”:
“Number of points” means that every Bezier curve consists of the same number of
drawn points. This is of advantage if the curve shall be morphed later.
“Density of Points” means that the number of the actually drawn points depends on
the length of the curve.
The option “last point of figure will be start point” allows for seamless drawing of
several Bezier shapes. Please test this feature to learn about the behaviour.
6.2.13. Separator:
The Separator Tool can be used for separating a line between two points by
adding an additional point in between. For using the tool, select the Separator Tool.
Then choose the color for the new point. Click on the target point of the line that
shall be separated and hold the mouse button. Drag (still hold the mouse button
clicked) the cursor to the position where the new point shall be inserted.
Supporting lines help in anticipating the result. With releasing the mouse button the
point is inserted at the defined position.
