Templates and Cross Sections

Hi,

I am working with OpenSite. I need a comprehensive tutorial/video/PDF on the cross sections templates. What elements they should have. End conditions and hinge points. 

Here is my case: I made template drops at residential driveways of the streets in my project. But, as I get cross sections, the cross sections at driveways do not have end conditions at the side of the driveway and therefore that cross section does not meet the Existing ground. I am pretty new to OpenSite cross sections and Template Menu. So, can you please guide me with tutorials/videos so that I can understand the issue.
