The following drawing must be supplemented by the value of the center circle point in order to be able to calculate the point
of intersection between the circle sector of the straight lines.

Activate the calculator when you are in any input screen.
Open the lower-level menu for contour elements selection.
Select the desired calculation function.
This function calculates the missing end point of the straight line/straight line contour section
whereby the second straight line stands vertically on the first straight line.
Press this softkey to define the given end point when the ordinate value is given.
Press this softkey to define the given end point when the abscissa value is
given.
Press this softkey to define the second straight line which is rotated counter-
clockwise by 90 degrees against the first straight line.
Press this softkey to define the second straight line which is rotated clockwise by
90 degrees against the first straight line.
Enter the PP coordinates, angle A, EP abscissa / ordinate, and L length in the respective input
fields. The following values of the straight line are known:
Straight line 1: Starting point and slope angle
Straight line 2: Length and one end point in the Cartesian coordinate system
Press this softkey to calculate the missing end point.
The abscissa value is displayed in the input field from which the calculator function has been called,
and the value of the ordinate is displayed in the next input field. If the function is called from the part
program editor, the coordinates are saved with the axis names of the selected basic plane.
The missing center point coordinate is calculated using the calculator function, as the radius at the
tangential transition is perpendicular to the straight line.
The radius is located at an angle of 90° clockwise to the straight-line defined by the angle.
