The procedure to draw any 2D-Primitive, consists of the following steps:
Select the type of object which can be drawn
Draw the object
The second step varies with each of the different 2D-Primitives. Therefore these are dealt with separately in the following where the operation is shown with the icon button to be pressed to select that function.
left-click (and hold) on the canvas where the freehand line is to begin
draw the line by moving the mouse with the left mouse button still pressed
release the left mouse button when the final point of the line is reached
left-click on the canvas at the point where the line is to start
release the left mouse button and draw the line by moving the mouse
right-click on the canvas at the point where the line is to finish.
left-click at the point where the polyline is to start
release the left mouse button and draw the first line
left-click at the point where the current line ends and the next line starts
release the left mouse button and draw the next line
continue with previous two steps until the final line is drawn, then terminate this line with a click of the right mouse button
left-click on the canvas at the point of origin of the Bezier curve
determine the rise of the curve segment at this point with the help line - left-click when satisfied
left-click at the end point of this line segment
position the help line to achieve the desired rise, if further curve segments are to be drawn, left-click otherwise right-click to complete the curve
left-click (and hold) on the canvas at the point where a corner point of the rectangle is to be
draw the rectangle by moving the mouse while holding down the left mouse button
release the left mouse button to complete the rectangle
left-double click on the regular polygon tool button
a dialog opens where the polygon parameters are set
make the appropriate adjustments
left-click the OK button when finished
left-click (and hold) on the canvas at the point of origin *
scale the polygon to the desired size by moving the mouse while holding down the left mouse button
release the left mouse button when the desired size is achieved
left-click (and hold) on one corner point of the bounding box * of the ellipse
draw the ellipse by moving the mouse while holding down the left mouse button
release the left mouse button when the ellipse is the desired size
* The bounding box of the ellipse is a rectangle which is just big enough to contain the ellipse - the edges of the rectangle are tangents (parallel to the x- and y-axes) of the ellipse.
left-click on the canvas where the text is to begin
type the text
