Attached are a 4 Lane divided carriageway (with Depressed Median) Template from Indian Template set. Referring the attached images, the Cross slope (Camber) is a for LHS is shown as +2.5% from Left Median edge whereas the Cross slope for RHS is mentioned as -2.5% from RME. Cross Slopes are generally negative slope (-2.5%), why is it showing differently ? I feel ORD is taking slope from left to right side and not from center/median edges. Since this is different, the Superelevation schematic is represented as -2.5 % and + 2.5%, which is not correct. Wonder if there is any setting that need to be corrected for this.

As a highway engineer I don't disagree with you. But the way ORD shows cross fall in templates is based around mathematics and how delta X,y are calculated from the 0,0 origin.
It should be noted that when you use Superelevation tools to override the template that the values are as a highway engineer would expect.
I agree it can be very confusing.

Thanks Chris for the reply. So I understand the Template signages are working fine, no issues with that. Let me know if I need to make any changes while using Superelevation tools to ensure the template signage is overwritten ?
No in the Superelevation tool you enter Superelevation as you would expect.
-2.5% for normal chamber+
+2.5% for super
