Back to Back Vertical Curves Without a Tangent

If you come from a Land Desktop background you are used to a PVI based design process. Civil 3D utilizes both a PVI and entity based workflow. Thankfully you can use either workflow. If you use the PVI based workflow if you want two verticals back to back you have to use a short tangent between them. If you use the entity based workflow you can attach vertical curves to each other.

To do this use the free and floating type of vertical curves.
