Corridor offset does not work on 00+00 station.

Question

I've run in to issue where my corridor doesn't offset properly a shoulder line. the blue line should start at the end of the brown line since it's the one used for offset geometry. It says it's on the start station(0+00) but clearly it's starting only few centimeters off the start.

Hi Reinis, 
 
 This is because the Point Control is effectively perpendicular at the Corridor start. 
 
 You can try increasing the template drop interval to get a bit closer, but the workflow to achieve an intersection like this is to take the corridor back a little bit, create a Terrain for the intersection part and apply a surface template.
