# Curve

## Description

A 1D curve is defined by its coordinate arrays.

CSX = AddCurve( CSX, propName, prio, points, varargin)


with the parameters

• CSX: The original CSX structure
• propName: name of the assigned property
• prio: priority of the primitive
• points: two-dimensional coordinates of the base polygon
• array column refers to point number
• array row refers to its x,y,z- position:

points(1,point_number): position-x of 'point_number'.

points(2,point_number): position-y of 'point_number'.

points(3,point_number): position-z of 'point_number'.

### Example

This example creates a Biquad antenna from thin metal on y=0, with length of each side=$\sqrt{50}$.


points(1,1) =  0;points(2,1) = 0;points(3,1) = 0;
points(1,2) =  5;points(2,2) = 0;points(3,2) = 5;
points(1,3) = 10;points(2,3) = 0;points(3,3) = 0.5;
points(1,4) = 15;points(2,4) = 0;points(3,4) = 5;
points(1,5) = 20;points(2,5) = 0;points(3,5) = 0;
points(1,6) = 15;points(2,6) = 0;points(3,6) = -5;
points(1,7) = 10;points(2,7) = 0;points(3,7) = -0.1;
points(1,8) =  5;points(2,8) = 0;points(3,8) = -5;
points(1,9) =  0;points(2,9) = 0;points(3,9) = 0;
