Arc

CP-P-P

You construct the circular arc by specifying the centre point as well as the start and end points. This function has 2 solutions. One solution shows a circular arc with positive orientation, the other a circular arc with negative orientation. In the case of a positive orientation, the circular arc is drawn anti-clockwise from the start point to the end point.

P/GE-P/GE-P

You generate a circular arc with this function if you specify two graphical elements (or two points) and one point.

P/GE-P/GE-Radius

You generate a circular arc with this function by specifying the start and end points and the radius (or angle entry). This function has 4 solutions.

P-P-Angle

You generate a circular arc with this function by specifying the start and end points and the central angle. The central angle is the angle whose vertex is also the centre of the circle. This function has two solutions.

Sketch

Arcs can be sketched without drawing a line beforehand.

The auxiliary circle is dragged equally up or down (depending on cursor position) from the first point. If the circle joins a line, it is displayed tangentially. Press RETURN to apply the radius and then the degree of aperture.

Next, sketch technology switches to the drawing of a line.
