This question was asked of us today - user had a corridor surface model thT they wanted to generate the surface using a sampling interval of 5’. They went to Project Settings and computations for corridors and changed the interval to 5’ but the corridor surface did not update - why is that?
The issue was that they had applied the sampling interval override on the corridor Template - Project Explorer - Corridor - Template and then properties - if that override has been used then the corridor surface is generated using the template sampling interval not the interval defined in the project settings
