im trying to make this part and i cant figure out how to make the teeth/splines. someone please help, im a new fusion user and havent done cad in years.
how to make teeth on a surface?
Accepted solution
From the picture it is hard to tell if the teeth are straight or have a radial taper, so I will guess and use a radial taper. Also do not know any sizes or tooth count. There also are other ways to make the teeth, I chose a Loft. Model attached.

There still is a lot of missing information so I will let you follow my method, if it suits, and use your dimensions. Let me know if you need help on your model. If you do, do not forget to attach your attempt.
If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

if you want the teeth from one disc to be able to fully mesh with a second one when placed together, then you have to insure that the peak of the teeth are slopping down, the valley is sloping up, and the faces of the teeth are planer and not twisted/warped.
attached is an example.
Attached you will find your defined model. The process I used is rather length and I am sure others may have a better method and shorter method. If you need explanation on how I created your model, let me know "personally".

I never heard a peep from you after posting your finished model. Did it suit your needs? Do you have questions about it? A little feedback would be nice.

It is a parameter.

If you have a Timeline, in other words Capture Design History, you use them all the time. Every value you enter, offset distance, dimension value, pattern count, etc is captured as a Model Parameter and can be seen by feature in the Parameter dialog box. You can create your own parameters, called User Parameters, and use them instead of, or along with, model parameters to control your model.

If you have to change the tooth angle, then the whole design must be revisited. If the diameter is maintained, the number of teeth will change. If the number of teeth stay the same then the diameter will change. Of course the general height of the teeth could be different and maybe maintain the count. Lots of variables

So what are your new design specifications? Obviously I cannot read your mind, please post them.

According to your design requirements the teeth taper to the center of the gear. Since this is the case, the angle you mention varies along the length of the teeth. I will have to pass on this as I if I try to model what you want, I am sure you will reject it and I will send a lot of time for nothing. Good Luck.
