Notice that Orionis98 shows a better start and finish. The real profile shall have a smooth curves at both ends of this junction road.

A better approach might be as in this file.

ramp-between-2-roads-at-90-degrees 3.skp

And the, the junction road could also have an horizontal curve so that the transitions between it and both roads are smoother than with a sharp angle.

type s for segments number: 8s
might be your case - many shortcuts are broken in the latest su build
p.s. never saw the need in this tool - circle is universal

If you push or pull a polygon, you get a polygonal prism.

If you push or pull a circle, the longitudinal edges are smoothed so you get a cylinder.

Of course, you can soften the edges of a polygonal prism to get a cylinder or unsmooth the edges of a cylinder to get a polygonal prism but this is extra work.

For a curve you have two choices :

1 - Use the same method as what was shown for a straight edge.

2 - Explode the curve then delete unwanted segments. Of course parts of segments can be deleted if method 1 is used.

See attached image.

My SU is in French but you shall deduct the correct option.

Bonjour.

Salutations.

Show hidden geometry to reveal softened edges.

Select as much as you can with a window select.

Use the Soften/Smooth Window and then move the cursor to the leftmost position. All selected edges will be unsoftened.

Hi Blanchon, hi folks.

This is what I get with SU 2021. I saved it as SU 2017 format.
