4.3.1.2.
Circle-Straight Line
With the function Calculate
> Intersections >
Circle – Straight Line the intersection points of a straight line and
a circle can be calculated and stored as plane coordinates.
Define the start and end point of the straight line by entering the point
numbers. Alternatively, click on the points in the graphic screen of GART-2000®
CE. Then
choose the center point and the radius of the circle. The straight line and the
circle are displayed in the graphic screen.
To parallel-shift the straight line enter the value in the field Distance.
A positive distance moves the straight line to the right, a negative distance
results in a shift to the left. The orientation of the straight line is defined
from start to end point.
For the circle the input of a
distance results in a shift of the intersection points on the arc. A positive
distance shifts the intersections outwards, a negative sign results in a shift
inwards.
With the <Option>
button other definitions for the straight line and the circle are possible.
By pressing the <OK>
button the calculation of the intersection points is started.
The result of the calculation
shows the plane coordinates of both intersection points.
To store the coordinates of
the intersection point 1 click the <S1> button; to
store the coordinates of the intersection point 2 click <S2>. Alternatively,
press <Mean>
to store the averaged coordinates of both intersection points. The coordinate
input dialog is opened automatically.
