Use this function to draw one or several linked Bezier curves. The curves are automatically linked together to get a smooth link.
The Bezier curve shape is defined by 4 points: two end points
First select the rectangle graphic object from the
Draw menu. Then click the left mouse button at the rectangle left upper corner, drag the mouse to the right bottom point of your rectangle and press the left mouse button. You can now start drawing another rectangle or select a new graphic object from the menu.

Arc defined by three points
The first mouse click defines the start point
To finish drawing the arcs, press the
Arc, chord and pie
Proceed in the same way as when drawing a rectangle but you will also need to set up the starting and end angles of the arc. Enter the values of the angles in the Properties panel in tenths of degree.
The procedure is similar to rectangle drawing but the inscribed ellipse is drawn instead of the rectangle.
Draws a polygon.
Click successively at the places where you want the vertices of the polygon to be located. After you have completed drawing the polygon, press the

Scale X and
Scale Y in the Properties panel. The length and width of the arrow are multiplied by these values. For example, the value of 1.23 enlarges the arrow by 23%.

- By clicking on line node delete a point (
Escto return to Selection mode
Smooth modification of Bezier curve control points
Ctrl key is pressed when a Bezier control point is moved, the program moves the opposite control point so as to make the curve smooth.
Select the line and set the line type in the Properties window. Use
Line type Scale property to change the size of the line segments. For example, a value of 1.3 increases the length of the line segments to 130%.
Select a closed graphic object and choose a type of hatching in the Properties panel.
