ELLIPTICALARC
Part of an ellipse, between two angles.
Syntax
ELLIPTICALARC centre,major,minor,start,sweep
ELLIPTICALARC @id,centre,major,minor,start,sweep,layer
| Argument | Meaning |
|---|---|
| centre, major, minor | The ellipse, as for ELLIPSE. |
| start | Where it starts, in degrees round the ellipse from the major axis (anticlockwise). |
| sweep | How far it goes, in degrees: positive anticlockwise, negative clockwise. |
The id, layer and any settings after it are the element settings.
Examples
P4=[250,200]
P5=P4+[200,0]
P6=P4+[0,100]
ELLIPTICALARC P4,P5,P6,0,180
The top half of the ellipse.
Notes
The angles are the ellipse's own (parametric) angles, as in DXF files: 90 is the end of the minor axis whatever the
ellipse's shape. Its ends are not its own points, so it can't be joined; the Ellipse Tool makes points at them,
ONELEMENT(@id,0) and ONELEMENT(@id,1), for other tools to use.
