SHAPING ELEVATIONS
When the track and the pitlane are ready we can move to the next step: adding the elevations to both parts. 
First of all Select TRACK -> TRACK DATA. Here we’ll see all the info sector by sector. For the pitlane the table is PITLANE -> PITLANE DATA:



These are the parameters to consider the most when planning elevations:
LENGTH (L): length of the sector. It is expressed in units.
ARC: angle of the sector. It refers to the curving angle of the sector.
DELTA HEIGHT (H): it is the amount of height given to the specific sector from the track sector dialog box. It is expressed in units and accepts values from 0 to 255.
ISO HEIGHT: it is the general height of the track and is expressed in meters.
GRADIENT (HxL): it is automatically obtained by multiplying the Lenght of the sector for its Delta Height. It represents the height of the sector at the end of it.
CUMULATIVE GRADIENT: it is the sum of all each sector Gradient from the starting line to that given point of the track.
ALTITUDE DELTA: general Delta Heights of the track. It is expresssed in meters and represents the overall elevation from the starting line of the track.
 
Since when any Delta Height is added, the rest of the track will follow that value in a linear way so it will raise or descend til the end. So our work is to alternate 
uphills and downhills untill the start and the end of the track will lay at the same height and possibly at the same inclination. If we have detailed info about the 
elevations of a track, the Iso Height will help us to perform a pretty realistic shaping.

Once shaped the elevations of the track, we need to do the same with the elevations of the pitlane. This work is a little harder than the track, because if the pit elevation 
and most of all its inclination will not match the track ones, we can see a step effect entering or exiting the pitlane. Also the pitlane may suffer of a not pleasant 
blending with the track surface by appearing on a different height level.
A way to create good elevations for the pitlane in accordance to the track ones is to set the length of the pit sectors as the same of the track ones. Then, giving them the 
same height changes than the track, they should move accordingly. Once crossed the pit entrance, it is quite the same, so, referring to the track elevations is a good way 
to quickly spot the right values. Here is an example of how the pitline strictly replicates the construct of the track:



For more reference, the connection between the track and pitlane, makes it so the last sector of the pitlane tends to anchor the sector where the 0x87 command (Connect 
Pitlane End) is. What may happen is in example that entering a positive value, which makes the pitlane raise, it will cause the pitlane to go down since the end tries to 
match its anchor sector and so on...
