Twist while extruding

[Helmi74]

I didn't need that for quite a while but I was quite sure we already had some easy twist option in Fusion360?

I'm talking about simply twisting a shape while extruding it. I thought it was in the sweep command but I don't seem to find it anymore.

Is my memory just wrong? I know you can like twist after creating a t-spline but this in my case is much more complicated.

Thanks,

Frank

I think it is Sweep with Path and Guide rail.

Loft with rails also works

Tool choice depends on what type of control you need. It maybe a sweep with the use of coil, sweep with splain as a rail, loft, loft with rails... many.

Simplest approach:

Thanks Michal,

gotta find the way with most control afterwards in terms of height, amount of revolutions etc.

In other CAD programs I have used in the past, I have seen helix listed under the extrusion options.  This would be very helpful here also, and make it much simpler to be able to define a base plane and extrude it with a helix!  Great potential for an update in the future.  I myself tried a way that works but takes a vast amount of computing power.  Draw a thin slice, around .001 thick, copy and rotate it, and do this over and over until the desired height is reached.  If you go very large with it, it takes a beast of a computer though!

did you ever find a way to control the number of revs here?

You can just do a simple Sweep with a Path. No need for rails. Once you choose the Profile and the Path, some additional options become available on the Sweep dialog box. One of them is Twist Angle.

Is it possible to manufacture this model on a 3+ 1 axis machine? Fusion's support of 4th axis work seems pathetic.

I do not know. I am not a machinist.

Cheers for that, Exactly what I was looking for.

Been trying to create a rifled gun barrel, and was struggling to get rifling to rotate using sweep.

I had no idea that there were extra options in sweep that didn't show up until you tried to edit the feature.

How dumb is that? Why aren't they there to start with?

Many thanks, I can start gluing my hair back in now, Haha! 🙂

It shows when you create the feature but not until you select the path. Also it will depend on what other setting you choose. It will not show with for example it's not available if you use path + guide rail or if you set orientation to parallel. The dialog changes to match your selection.

This is what you should get while creating the sweep as soon as you select the path.

so it's not twisting for me... can anyone tell me what im doing wrong?

[wmhazzard]

For some reason it won't twist with the center hole. Make it solid and it should twist and then cut the center hole out afterwords.

wow thanks!
