LTDesignZ
​
LTDesignZ[vips,ch]
gives the design level (RL) at chainage ch by linear interpolation between the vertical intersection points vips, a list of {chainage, RL} pairs. A chainage beyond either end clamps to the first or last VIP. Use LTDesignZCurved to include parabolic vertical curves.
​
Details and Options
▪
The vertical intersection points are sorted by chainage first, so they need not be given in order.
▪
This is the straight grade line between VIPs. Use LTDesignZCurved to apply parabolic K-value vertical curves.

Basic Examples  
(1)
Halfway up a grade from 10 m to 20 m over 100 m:
In[1]:=
LTDesignZ
[{{0,10.`},{100,20.`}},50]
Out[1]=
15.
