how to create curved driveways with thickness

[AzjahGreen]

Im not sure if this is an actual thing, but i am trying to figure out how to draw a custom driveway that slopes and has thickness to alight with the garage. also having a roof issue not wanting to rebuild for the garage. any solutions?

Without seeing a plan, I can only speculate but you'll probly want to use the polyline driveway tool and use some elevation lines to create the slope. Driveways by default will hug the terrain. If you're needing something where the driveway is rising up from the terrain, I would look into using terrain breaks on the side of the driveway and then some foundation walls to make the supporting retaining walls.
