making a ramp for a toy car road

[Anonymous]

hi

i drew a road for toy cars and I wanted to make some ramp on it but I couldn't. maybe it is very easy job but I couldn't figured it out. I just attached the file and what I want as a picture circled the ramp. for this I created 2nd sketch to raise a ramp but it wasn't like a ramp rather a tower then I created 3rd sketch and projected 2nd sketch geometry in the hope that I can link it to the first sketch and create it by applying some fillet but again I couldn't. so what's the trick here? by the way the road is 80 mm wide and the sides are 10 mm high and I want the ramp be like 250 mm higher than the bottom road at its peak point.

Use a vertical sketch, for the profile of the hill, then sweep the track on the path.

thank you very much for your answer your ramp has been perfect but there is a gap in between the end of the curve and other point of the road. how to close that? plus I try to make that blue ramp in the picture I circled to the other side of the road but I can't again. can you help me in this too? it can be like 150 mm high and the top straight part of it should be straight as in the photo. thank you very much

and why did you create a project feature along with the road? I didn't get its logic, actuallyy I couldn't. a screencast would help a lot

Project the track face into the vertical sketch, saves me drawing it, is no need to do something twice, and accurate, so you have some thing to dimension the height.  Change them to construction,

Edit my sketch, change it to what you need, 2 straight lines and 2 tangent splines.  The Sweep will break, but Edit the Sweep and update to the new path.

Gap in the connection, - don’t remember that happening, your 1st sketch is not fully constrained, all but one line is blue, did you or Fusion? move something.

I didn't move anything actually I realized the gap as soon as I opened the file. I think I closed it with a pull press feature (I don't know if it is the best way tho). Im sorry to disturb but the next problem is I will print this road with my 3d printer whose limits are 22x22 cm so I split the model into pieces and I created puzzle joints in between the pieces. There is not problem with straight pieces but the pieces belonging to ramp has angles in between so when I try to create those joints these happens I posted in the photo below. But what I want is to make them in the direction of that red line I drew. I create them and them combine with the next piece selecting cut feature and then give some offsets

Those tabs, should be drawn on face of the track, like the others, you have them horizontal, so fix the sketch to be on the track to join.

Press pull is not a good thing to do, when you only need to make the my sweep profile face 90 degrees to path. (Vertical constraint in the sketch.)
