The polygons may have four Directions, which are calculated by the program:
To calculate these Directions, the program divides the polygon into 4 sectors and determines proximity in which sector each segment is.
Consider down your chim image:
North is indicated by the blue line. The sectors are divided by red lines.
Then the segment 1-2 is to North who from within the plot outlines. The segment 3-4 is to South. The segment 2-3 is to East while 4-1 is to West.
The properties of a Directions are:
| Property | Type | Description |
|---|---|---|
| Start | Integer | Number of start vertex |
| End | Integer | Number of the vertex |
| Name | Text |
Name orientation.
Can be:
|
| Description | Text | Description of orientation |
| Start Vertex | Expansive | Start vertex |
| End Vertex | Expansive | End Vertex |
| Length | Dimension | Side length |
| confronting | List | List of confronting side |
| Segments | List | List of all segments of the side |
