I have been struggling to make a smooth pinball ramp. Here’s what I have so far:

I am using “shell”, but then I can’t remove the ends of the ramp. Also, the bottom curvature is really weird. I need it to be a smooth transition all the way up. I’ve tried a few different ways of making this but none have given me satisfactory results. Any help greatly appreciated.

Is this good enough?

Close but not quite. A pinball won’t be able to climb a ramp that steep. How did you make this?

That just a quick test. Form can be changed as you need it.

Same way as I described yesterday here:

> Basic technique. I just used two profiles and extruded them with Intersect.

Hah! I looked at that thread and couldn’t figure out how to make the shapes intersect

Here’s what happens when I intersect. The bottom of the ramp gets twisted and part is lifted off the floor. Also, I can’t figure out then how to shell the ramp to take away the top and ends.

When drawing the sketches, they should match each other perfectly. The easiest way to create the second sketch is to use a projection of the extrusion from the first sketch and constrain it to the shape of the object.
