Sweeping

[wweikert]

Hey guys,

I'm trying to sweep a profile along a curved path. 

What can I do to keep the vertical lines of the profile vertical? Right now the profile is 'tilting' into the curve, but that's not what I want.

Here you can access my design: http://a360.co/2zsurZt

Thanks in advance!

Well... i dont know if I understand correctly, but it is tilting, because you created it it tilting.

I attached my file, where it is vertical to the line, because it sits on it vertical. But maybe I didnt understand something. 

[wweikert]

Thanks for your answer!

This tilting angle was actually on purpose. 
What I want is to keep the bottom line of the profile horizontal at all the time. 
This seems to be more of a geometrical Problem.

This is how far I came by creating a 'guiding rail' (German: Führungsschiene):

But I want to avoid the marked corner to be smooth. I guess this won't be possible using 2D sketches?

[Ezekiel12]

You mean, like this?

[wweikert]

More like that but with the marked corners smooth:

create a plane along path using thee curve and then sketch your profile on that plane

[wweikert]

This is more or less the object I wanted to create. Any ideas how to do that in Fusion?

[jasonhomrighaus]

Just to understand you want the curved areas to be tilted onto a different plane then the long areas?

[wweikert]

The curved parts actually aren't on a plane, more on a curved plane.

If you think of the inside of whole object as a tunnel, I want the floor to stay horizontal all the time.

[jasonhomrighaus]

Well this is one try at it.

[wweikert]

Thanks for your help, but this object has the same problems as in Post 5. 

The Object I created with another Software is pretty close to the one I want to create in Fusion.

Here try this one, i used an offset guide rail then selected the profile and guide rail option, can make a vid if you want to flatten the base I used an offset plane and split the body, from there you could sweep on a base profile on the flat plane if you wanted.

Your tunnel is doable, but not completely with sweep, you need the U-turn to be a Loft, due to the change of profile orientation involved at the centre of the end path curve.

you may have to realign - redesign the profiles to suit your design, 

you and @jasonhomrighaus, have yellow warnings to avoid and fix.

file attached , edit my loft feature to see the settings, 

might help....

[wweikert]

Thank you all very much, @davebYYPCU thats exactly what I imagined!

[davebYYPCU]

No problem, happy to help if I can...

The yellow warnings was because I deleted bunch of extra sketches i had in there.  The Sweep feature allows you to do this without the lofting step, the difference is to have an offset guide rail.  it will leave a short gap as the sweep cannot self intersect but a quick extrude closes it all up.

Im still not sure i understood, you wanted the floor to curve like that in the corner?  if so just do what i said but dont cut off the bottom edge. this is how it looks before being cut

[wweikert]

You're right @jasonhomrighaus, without cutting your solution is like I thought, thank you. I'll look deeper into that tomorrow. Thanks!

[wweikert]

The final result:

I used lofts for the U-turns and sweeping for the straight paths.
Sweeping alone led to a tilt at the lower U-turn, at least with this profile and radius.

I have been trying to figure out why sweep wasn't working (OK button always disabled) and you simple little comment solved the whole thing!

I have watched videos from Fusion, read the documentation I can find, and NOTHING says that for a simple profile/path sweep to work, that they have to be somehow connected.

In my case I used your idea of the plane along a path and did my profile sketch there with one corner coincident with the origin.

Thank you very much.
