Learning fusion, need advice on achieving a specific geometry

[Anonymous]

I'm trying to model up a replacement beyblade part to 3d print it for my son, and there is a particular part on the shoulder I'm having a hard time modeling. Also, the snap feature is rather confusing. What I'm used to being able to do is constrain a line on an axis, and snap to an intersection being made by it (like drawing a cord in a circle), but fusion either snaps to a point in a grid or its freehand. 

In the part I'm trying to model I have tried using the revolve and the fillet tools to produce this geometry. I may not be using it correctly. The purple I modeled in a different cad and imported it.  

Please look at the picture provided and if you have any advice on how to draw the shoulder piece I would greatly appreciate it. Thanks.

First thing  I would do is turn Capture Design History on. (After Convert Mesh to Brep.)

You'll see after I tried using what I learned in the tutorials, I tried a direct modeling approach in the sketch, which failed even more spectacularly than the other approaches.

As far as i can tell, it's supposed to be on... Maybe something happened when i imported the other model?

Also i am not using the mesh, i just imported it as a template to show what it was i was modeling. Its a new solid drawing.

So, your thinking revolve a profile, then removing material I don't need as opposed to building it up in layers?

I think i can see that working, as I would only need about two more sketches to remove the excess material. 

Is that what you are trying to tell me?

Work your way through the Timeline history.

30 minutes - including time to document steps.

I was really only needing direction. I appreciate all the work. I'll work through and see what all was done. Btw I wasn't asking for the other sketches, I was just wondering if it was the direction you had in mind. 

Thanks.

Ok, last step I am missing is, I cannot seem to convert the mesh to brep. The option should be located under the convert button but It is not present. Am i doing something wrong?

Right click on the Mesh body before turning one Capture Design History.

Never mind.  Had to convert to component then it allowed to be converted to brep, now its very easy to snap. Thanks. this will make the rest of the day go by fast. 

Thank you very much.

This is the second part I was able to make today. Didn't have time to do  much, but I did complete both pieces to the broken part and I can assemble it after work tomorrow. Just wanted to say thanks. 🙂
