SWEPT 'rotation'

[emenes]

How can I 'rotate' a swept during the operation ?
In attached picture I tried to explain what I would like to do/become.
I thought it should be possible to 'rotate' the swept over a certain angle ?

(The workaround is working with a law controlled helix or contructed spline)

I once saw a YOUTUBE movie on this topic, but can't find it back ...

Thanks for your help !

regards

The corporate firewall is blocking your picture for me, so I can't see your example. But, if you are using a single guide; you can use the "angular law" orientation option. This will twist the section along the guide.

Hi COWSKI, thx, but that's not what I haeve in mind.
The twist should be around the main-part axis, and not along the guide itself (Or did I do something wrong)

How can I get the picture visible ?

It depends on where you upload your file. If you use the attachment link below the reply box, that location always seems to work for me (it may be different for others).

Works for me. Unfortunately, I don't know of any option within the swept command that will produce the 'expected result' given the section and guide shown.

I think your best bet would be to create the guide that gives you the result you want. Here are a few methods that I would try:
[ul]
[li]copy your existing guide over by 30°, use a bridge curve to get the 'S' shaped transition[/li]
[li]draw an 'S' shaped curve on the bottom plane and use "combined curve projection" to get the desired guide[/li]
[li]it appears that the guide is at a constant offset from the 'bell' surface. If so, create an offset surface at this distance then use the curve on surface command to create the desired guide.[/li]
[li]Perhaps it is possible to deform the swept after it is created by using X-form or global shaping. I'm not sure that either of these will work for you; I've only used X-form on sheet bodies and I have very little experience with global shaping.[/li]
[/ul]

Thanks, these are indeed workaround options, but I'm pretty sure there was an options to do so...
I'll spent some more time on youtube to find the video

thanks anyway !
