Making curved slots around an axis

[Anonymous]

Try as I may, Fusion 360 tutorials never seem to grasp my lack of CAD knowledge. Anyhow, the problem at hand is that im designing a part that requires a hole with 4 curved bolt holes areound it. This is so the shaft can go through the hole and the adaptor can be rotated (clocked) around for proper allignment. Here's a pic of what im trying to do, rendered in CAMBAM:

Hey, thanks for reaching out. Are you looking for guidance to how to sketch this in Fusion 360 or are you looking for something else?

Hi, and yes im really wanting to learn this:)
Im looking for both actually. Ive become a CamBam wizard over the past few years but know I can do MUCH more with Fusion 360. Learning how to sketch something like this would be great.

Gotcha. Here is a great video to get you started.

Let me know if you have more questions and I'll be glad to help.

I've attached a file with a fully parametric sketch to do the curved slots, just edit the 3 sizes and leave the dimension with fx alone. It's a bit difficult to explain, I do a screencast later.

Actually I would create only one of the slots in the sketch and create a feature pattern.

Would it be possible to replicate the slots in an array around a center?

[TrippyLighting]

Yes, in Fusion 360 that is called a circular pattern to be foud in the "Create" menu.

An Array is a rectangular feature pattern.

This has nothing to do with my question but I just have to add that you guys are the BEST! Not just in technical forums, in any of the communities ive been a part of over the past 15 years. Im new here but ive come to know I can count on you guys and (occasional) gals.

Thank you, in all sincerity.

OK, so in this video he uses a circle tool at seemingle random points, then switches to a line tool that suddenly produces curves to make his profile. What kind of dark magic is this? It didnt work when I tried it.

EDIT: Nevermind, I got it.
