How to model a triangular notch?

[Anonymous]

Hello everyone,

so I managed to take my GoPro mount a little bit further by designing some additional elements. Now I'd like to add a triangular notch to the mount so the camera doesn't slide out of the mount. The notch is on the back of the mount and should go around the case.

Things I already tried but failed:

- Extrude the back plane (square with round edges) -2mm in the inside (of the case) direction and try to make a shell to get a kind of ring that connect to the case. This is not possible because of errors (can't remember the exact message) appearing in Fusion 360. I think it's impossible to create a shell out of it geometrically.

- Extrude the back plane (square with round edges) -2mm in the inside direction and then drill a hole. I suppose you can't drill holes in the form of a square with round edges, but that's logical so this was a bad idea to begin with 😉

- Then I tried to create another back plane, make it smaller and then do a diff so I would get a ring body out of it but I have no idea how to make such a budy smaller. I was trying using dimensions but that's not possible because of too many constraints already in place.

I'm attaching 3 images so that you can see what notch I am talking about.

Case state right now.Missing notch.Original mesh with the notch at the back.

So do you guys have an idea for steps on how to model the triangular notch? I'm not asking for a hand out, I'd like to model it myself but don't know how.

EDIT:

I think the triangular form can be achieved with a chamfer at the end but first I need to create a smaller "ring" and attach it to the back.

EDIT:

OK, I think I know how. I need a while but I think I know 😉

Kind regards

Yes, so the steps are.

- Sketch a small back plate for extrude operation.
- Extrude the ring -2mm.

- Use chamfer with 2 distances.

I see that you've taken the advice form "the other thread" to heart and have remodeled that .stl design.

Can you share your model ?

I'd like to try my hand at improving your filleting skills 😉

To be honest @lichtzeichenanlage delivered almost finished case so now I'm only adding few last things. I'm attaching his model and my current result.

OK, the screen cast just blew my mind. So freaking easy. Sweeping along a path. Can't believe how long I was thinking about my ugly solution.  

Thank you for showing me that!

But, what you call your ugly solution required you to explore some of the tool functions in Fusion 360 and trust me, that will come in very handy some day soon.

Just re-modeled the notch with sweeping. So much fun. I should quit my job and sweep all day.
