unable to make transition from a plane to a curved shape

Hi, I'm newbie to fusion360. I'm trying to design a sloped corner for skatepark / RC car track. The point is to make a smooth transition between our common plane (ground) to curved shape of the corner. I attach a picture hoping clarify scenario. 

Already tried loft but can't make it to follow the path I liked, only a linear pathsloped corner.png

Unless you allow for some rounding of the corner highlighted in red, making that "really" smooth is geometrically not possible. The best you can do is to apply a few patches in the Patch workspace and sew them together into a solid and combine them with the rest.

What @TrippyLighting is talking about with the lack of smoothness...

But you CAN make the single Patch flatten out if you just add a single line to use as an interior guide during the Patch operation.

Hi, thanks for your quick reply!. I'm so sorry but as I mentioned before I'm very very newbie and don't know how to use patch.... May I have to create a sketch and a line for rounding this corner? 

 

I tried to patch the surface but nothing happens....

You'll have to disable "Chain selection" in the dialogue. Then you can pick individual sketch elements and edges.

That lack of smoothness is not what I was taking about. What I meant is that there is not way to connect these 2 surfaces in a tangential, or curvature continuous way. There will always be a sharp edge.

Oh yes, of course.
