You can use the Allplan Ramp add-on to create any ramps. A dynamic reference surface is created for the left and right edges using an axis, the length profile and any transverse slopes. You can then connect to this reference surface with architectural components such as floor slabs and walls.

Function overview:

-Take over axis with lines, circles and clothoids.
-Any length profile -Separate cross slopes and track widths for left and right
-Boundary axes for left and right ramp edge -Offsets on the axis for the ramp start and end
-Ground plan representation with heights, cross slopes and stationing
-3D representation as Brep and 3D surfaces
-Automatic reference surface for architectural components
-Uniform division of the reference surface
