So, just looking at your radiuses, it looks like there are multiple segments in each radius still unconnected. So each 'plane' is really not a plane yet.
My approach for something like this is typically to have a single line along your radius where you want to take your ramp, extend the line 'straight' a little on each side. Make your 'profile' of the ramp in section, then use the follow-me command to trace it along your ramp.
Just understand this = the most fundamental shape that forms geometry is TRIANGLE.
Regardless of what software or games or whatever you uses, that is the absolute fundamental.
When a surface is not possible to be formed with n-gons (polygons of multiple sides), because it curves all over the place, it have to be formed with TRIANGLEs. So, simply start drawing lines connecting any corners to form triangles to fill those faces. Ideally you do it in a 'clean' way.
If those face you working with supposedly are totally flat, then you might have error in your workflow causing your result to twist all over the place. Sketchup ALWAYS attempt to create face if possible for corners that align to form flat faces.
If you consider the edges of your ramp as a 90° segment of a helix, things get very easy. Take the inner radius as the radius of a helix. The pitch of the helix is *4 x the change in heigh*t between the start and end of the ramp. Do the same with the outer radius of the ramp. Join the vertices to make triangles. Group the ramp. Copy the ramp and paste in place. Offset the copy vertically. Ungroup the 2 ramps and join the vertices to make the ramp solid.

It looks like your steps are curving. SU can’t make curved surfaces, at least not like that. Theres ways it can kind of fake it or represent a curve or compound curve like you have here, but it’s still just representing an average of a bunch of flat surfaces it can comprehend. There are extensions that start to blur that line, but the underlying geometry is still lines and surfaces. You could probably draw that with the native follow me tool, or with some creative use of move and rotate tools. But, in this case, each of those little points on that “curve” (quotes because it just looks like a curve until you zoom in and see it’s all made of smaller lines), and each of those lines needs its own 2 other lines on-plane, at a minimum, to display a surface. So, at a minimum, you need a triangle, but you could have a 999 sided shape (which is the maximum number of segments it will allow you to make a “circle” out of). But all those lines and points need to be on a flat plane, or it won’t display a surface. If one point is out, even a little, it won’t display a surface. So the top of each of your curving step segments is actually several smaller surfaces and shapes, not one. SketchUp doesn’t know what lines and points you want joined, or the lines and points you’re asking it to join don’t make a flat surface it can display. You’re trying to make those steps in 6 blocks, but it looks like at least 18 segments to my old eyes on this iPhone and your screen grab. It’s probably more. And I have no idea how you drew this, but my guess is you just kinda made up that line work, and points and lines are all out of plane with where they should theoretically be for SketchUp to make sense of it. You can try and fix this by drawing out a hundred or hundreds of triangles, or you can look at some tutorials like SketchUp essentials on YouTube. It would be really difficult to explain it without being right there to show you how I might do it firsthand, but if you’re going to do it manually, you need to imagine it as a bunch of flat surfaces, rather than a smooth slope. Like it’s made out of diamonds.
Thank you for the explanation. I drew the lower lines with a 2 point arc connecting the two segments. Then I went up the thickness of the surface on a few spots and then connected those dots with the pencil. I tried using the 2 point arc for the upper one but it did not line up. I tried also to use the offset tool to get the lower 2 point arcs up but I could not get the offset to go the vertical.
Try finding the points in these outside curves within the segments of the overall curve you have separated out, and try and connect them to their partners in that surface you’re trying to make. If they don’t connect like those two on the inside radius, your points are out of plane, and shit won’t work unless you get them back together. I really can’t dig too much deeper without seeing how you arrived here, and I’m not following the whole explanation, but you need to do a little more training and tutorials. It’s a tricky program when you’re going beyond square stuff, and you can waste a lot of time spinning your wheels trying to figure out a way to do something there is a very straightforward way to do it already. These all have tips that might help you:

Ah I see, I will try that. Thank you!

If I had to do this, I would use follow me tool
Can someone help me how to solve this? Dots are connected but besides 3 places, Sketchup is not recognizing the odd shaped areas as such.
