creation of an intersection

[fernandezfz21]

Greetings, please help me with respect to the creation of an access, I would like you to explain step by step the use of the intersection command, for the creation of it.
Greetings and many thanks, attach the file cad

The intersection wizard is very straightforward to use;

1. To start, you need two alignments that intersect and each having a vertical profile
2. At the point the alignments intersect, the vertical profiles must also meet at the same elevation
3. Once you have these, start the intersection wizard
4. The intersection wizard allows you to set the offset parameters (lane widths), corner radius parameters and lane cross fall parameters (its best to know these before starting)
5. The intersection wizard will then create a corridor that can be edited further if required in tool space under intersections.

From your file it looks like your next step is to create the alignment for the access you require and then its vertical profile that ties into your main road

Making a intersection is no easy task. I don't think is realistically possible to explain everything on a forum.

Some tips: You have some problems on your surface. Add  top (or bottom) overhang correction to your surfaces. See attached image.
