Sweep failed

[Ap20003385V2]

i am trying to do a 3d print of the nurburgring and have made a spline that i now need to use sweep on

but i get this error

Create sweep feature failed
Nordschleife neon sign.ipt: Errors occurred during update
Sweep1: Could not build this Sweep
A segment of the sweep path is tangent to the profile (or is contained by the profile plane). Change the path geometry (e.g. make it perpendicular) so it is no longer tangent to the profile.

I have spent the last hour trying to resolve it but i dont know how

The dimensions of your outline (sketch4) are very large for the indicated path with a large number of small radius bends.

The problem of self-intersection of the contour arises.

When the size of the sketch is reduced by 10 times, the operation is performed.

Try making the sweep path smoother.

You should also attach (coincide) some sketch point (for example, the middle of the bottom segment) to the path.

Hi! Inventor Sweep was not designed to tackle a shape like this. I don't think it is doable using a sweep feature based on the given input geometry. But it can still be done using surface modeling technique. Please take a look at the attached part. Create a Ruled surface based on the path. Then I offset the surface in both directions. Create a solid body from the surfaces and the workplanes. Add a G2 fillet to some edges to smooth the sharp corners. Lastly, shell it in the desirable distance.

Many thanks!

sweep을 하려는 단면의 폭이 6mm인데 path를 양쪽으로 3mm씩 offset해 보면 서로 겹치게 됩니다.

즉, sweep 형상이 경로를 따라 겹치게 되면 sweep이 되지 않습니다.

또 sweep 경로의 최소 회전 반경이 sweep 형상의 폭과 같거나 작으면 안됩니다.
