SECTOR
Guide Section: Diagramming
EASAP Tree: USER INTERFACE → DIAGRAM LIST → DIAGRAM
SECTOR draws a sector of a circle ('pie slice') or an annular ring.
- SECTOR is defined by the parameters below:
- An origin point about which the sector is rotated,
- The inner and outer radii of the sector,
- The starting and ending angles of the sector.
To specify a SECTOR of a circle, set the inner radius to zero.
To specify an arc of a circle by setting the inner and outer radii to the same value.
An angle value of zero is from the origin out along the positive x-axis (horizontal); angle values increase in a counter-clockwise direction.
The Angles: parameter accepts inline units of deg after the angle values to change from the the default units of radians.
 SECTOR |
|
|---|---|
| Essential Parameters: | |
| Origin: | Point coordinates at the center of sector rotation: x0,y0 |
| Radii: | Inner and outer radii of sector: Ri, Ro |
| Angles: | Starting and ending angles in radians: a1,a2. The zero angle is aligned horizontally from the origin out along the positive X-axis; angle values then increase in a counter-clockwise direction. |
| Optional Parameters: | |

| Fill Style: | Select FILL STYLE from list. (default→Black, Opaque) |
| Line Style: | Select LINE STYLE from list. default→Transparent |
| Transform: | Select one or more TRANSFORM from list. Order selected is order applied. |
