Description |
across |
number |
undefined |
Metres across, positive to the right of travel, measured from from. |
from? |
"left" | "right" | "center" |
"center" |
Where across is measured from: the centerline, or the track’s left or right edge. A point measured from an edge keeps its distance to that edge as the track widens, as a shoulder does. |
height? |
number |
0 |
Metres above the track, along its up. |
spans? |
number |
1 |
How many strips the surface from this point to the next is cut into: more follow a lift more closely. |
wall? |
boolean |
false |
The surface from this point to the next is a wall face: it shades flat from the crease, rather than blending into the ground beside it. |
