Circular Ramp

[glenn.mause]

Hi, I want to intersect between two platform with a ramp following a quarter circle.

This is how the platforms are positioned from the side:

And from the top:

The ramp should follow a path like this:

And connect both platforms.

I looked into using coils, but apparently you can only use squares with those, but I would need rectangles.

Maybe I am not understand exactly what you're getting at, but why not extrude the circle you have by trimming the unnecessary sides and using lines or arcs to form the ramp to the desired size. This is what I was picturing.

Or if you were meaning an arc shape instead:

I hope this helps. If this wasn't what you were looking for then I may need a little extra explaining.

@mavigogun, I figured there was a great possibility I was misunderstanding. That looks good though.

A coil would be the easiest way.  Create the coil using a square profile, then Press Pull one side to make it rectangular.

@glenn.mause How about the attached file. You didn't specify the height of the platforms, next time you need help export the f3d and attach.

Could you demonstrate that?   How would the lead in-out to the ramps be effectuated using Coil.    To what degree can you use Coil to hit an exact elevation at any given point of the arc?

Here you go.  Note: No sketches were harmed in this screencast

Extruding the end faces will create the landings.

Nice demo of the tool- I learned stuff.   That said, imagine driving that ramp- the lack of transition to the landings would be excitement for a jacked up 4x4, and no fun slow or at speed for urban vehicles.   Actually, a functional ramp would benefit from a camber  for its length, too.
