How to create a spiral or helical cut

[GPTech2444]

Hi, I'm trying to model a stepper motor coupling and I'm trying too recreate the spiral cut that runs around the center of the coupling.

I've created a sweep cut but the cut will only goto 1 on distance and this is only 180 degrees, I need the sweep to continue another 4 times around the part.

Hopefully this screencast shows what I'm trying to do clearly.

EDIT:

I just worked out what I did wrong, the path was interupted by the cut from the side, but I still can't get it to do a spiral cut, I follow up with another video.

Here's the follow up video I just did, I'm still not getting the cut I'm after, the cut lays over as it moves along.

Hello GPTech2444,

Is it something like this that you want?

Kindest regards,

Thanks again Ludo. I didn't even think of doing it that way, I was over thinking it.

Hi Grant,

Overthinking, maybe not. Actually your design method should just work. But it does not, I ran into this ''rotation'' issue a few times, it is a known limitation of the algorithm used, however the Fusion 360 team has a solution which is planned for the future.
For the time being we have to use ''creative work arounds''.

Glad to have been of help.

Kindest regards,
Ludo

Local files not supported. couldn't you just describe the steps???

Hello sextant08,

To use downloaded files you need to upload them to your own account.

Local files are indeed not supported.

For the moment I have no access to a computer, if you need additional information, I can reply you in a couple of hours, sorry for this delay.

Best regards,

Ludo

You can open local files, use New design from file. Also no need to zip, the f3d file is a zip file if you change f3d to zip you can see the contents.

Hello Mark,

Original post is from february, then you had to zip a f3d file in order to post it here on the forum, now we can add as f3d.

The New Design from File, escaped me this morning.

Thanks!

Best regards,

Ludo

I only looked at the day part of the date, didn't spot the month changed.

Yup, got that part about loading a file figured out. Still having a problem with the spiral cut. I loaded and can see the steps in your Spiral Cut model - but can' figure out how you got the spiral.

The design i am working on is a bronze bearing with an ID oil groove. Your approach to spiral cutting would work perfectly except the steps in the time line don't indicate where to find or how to insert the CoilPrimitive2

[HughesTooling]

Here's one way. First select an end face and create a plane at the level you want the coil to start.

Then from Create select Coil and select the plane and pick a centre point then setup something like this.

When you're happy click OK.

Finally figured it out. the post on how to create a square thread helped by showing the steps a little more clearly. The address below is where I found the answer.

Hello sextant08,

As @HughesTooling pointed out, you can open a local file with:

The Coil is made with the Coil command:

In this case it was a square coil.

The Coil also needed to cut through the tube thickness:

For this an Offset to one Face of the square Coil was applied.

Hope is of any help.

Hi sextant08,

Our posts crossed, I see you already found what you needed.
