Improved helix (for helical gears, among other things)

[jkelindberg]

I would like to see the helix feature a bit more flexible to use. I'm currently trying to make a helical gear, but it's proving elusive with the current set of tools. The most obvious problem is of course that you can only select circular, square or triangular cross section for the helix, whereas on a helical gear you would want to use your involute profile to cut with. Second problem is that the cross section is tangential to the diameter of the helix, and for a helical gear you want it to be oriented axially.
So to make a long story short;1. User defined cross section sketches2. Orientation of the cross section (tangential/axial)Another way would be if it was possible to make a helical curve in 3D space and do a sweep along that curve, but this is not possible either (as far as I know)

Sorry for posting this twice, but the formatting got screwed up...

I'd love to see that as part of a generic gearing tool.

[cekuhnen]

very agree - currently the tools feel a little basic

Agree.  I'm in the medical field and to create an ISO standard lure thread is a challenge.

+1 for this 🙂

I just had to create some tapered threads, would've been so easy if you could specify your own profile.

My first attempt was to create a tapered helix and include the 3d path in a new sketch. Then i drew the thread profile and tried to sweep it along the path. Unfortunately this didn't work as the profile would rotate on it's way up the helix.

So i had to create another tapered helix to use its path as a guideline. I had to calculate a height and diameter offset based on my thread parameters. Luckily you can use triangulation functions in your equations.

In Inventor it takes a few seconds to generate such a thread, but this is just ridiculous...

Agreed. Its a major tool that's left out of fusion 360. Even onshape has it...

[redargon]

Twist compensation would also be a plus point. That way, you could use a coil as a path, but the profile that you want to sweep won't twist with the helix.

[Reenforcements]

Custom profiles is definitely essential!

Bring finally a tool to create helical curves with variable pitch, and free us from cheating with the coil command.

[huguesacker]

We need a simple tool to make helical objects. The coil cannot do that; it is limited to squared and circle faces.

I don't know if this is the place where to insert this answer.

Can you help this article ? Create an Helix following a spline

I would love to see a feature like this.  Be able to make a profile drawing and sweep around an axis while specifying an incline angle, or selecting a profile to follow and an incline angle!

I wrote another article about the Helix world ! It has been published just in these days on the Autodesk Help Blog.

This is my solution to your issue.

Maybe it can help you to better understand how to create more complex model .
