Extrusion from two faces at different angles

cbarham84 — Fri, 24 Jun 2022 06:27:28 GMT

I have a wedge shaped body which needs an extrusion along 2 different faces which ultimately gives the hole a bit of an angle. I created a plane along a path between two points and was able to extrude the initial hole just fine.

Where I am running into a bit of a problem is I need an extrusion along the same exact path, with a slightly bigger slot, however I need one side of the extrusion to not go to the end of only one of the faces. This will allow me to screw it onto a wall and have a flat surface from the larger slot.

I'm sure that was about as clear as mud, but any help would be appreciated.

Can you share (export to *.f3d) and share it here and a picture that shows what you want to do?

Thanks for the reply. In the picture you'll see the highlighted oval. I'm trying to create a slot slightly bigger than the one in the design, where the highlight is, and I want it to follow the same path the smaller one is using, however I don't want it to go all of the way through. I want to stop it shy about 1-2mm. I tried an offset plane, but I can't follow the same path that way, and I can't figure out how to extrude along the path but stop shy the 1-2mm distance.

Like this?

Thin Extrude, 2 sides, to Object (outside faces) with Offset to inside -1mm

Might help....

~~Is this what you mean?~~

Still not sure I understood correctly, I might be wrong. But if it is correct note that I did not cut a bigger slot but added a lip to the end. You need to edit dimensions in Sketch11 to that of your "slightly bigger" slot.

~~By the way, Fusion does not have extrusion along a path, extrusion is normal to profile. Another way might be Sweep which has path.~~

Forget it, @davebYYPCU 's Thin Extrude is way easier.

@cbarham84

Before you start developing poor modeling techniques -

Edit Sketch1.

Attempt to drag one of the two corners of the triangle not at the Origin.

What do you observe? (Missing Horizontal or Vertical constraint.)

Also, for the first year I recommend that any time you are tempted to use the Move command you stop and first ask questions here. There are appropriate uses for Move, but it is almost always used incorrectly.

This is exactly what I was looking to do. Wayyyyy beyond my beginner expertise, as I can't even follow what you did there...LOL But it is exactly what I was looking for. Would it be too much trouble to do the bottom slot the same exact way? I appreciate your help with this. Thank you

I couldn't agree more. This is my first relatively complex model and I admittedly had some fits along the way. I tried to use vertical and horizontal constraints and almost every time I would apply them I would get the over-constrained error. I the would remove the existing constraints and try again, only to get the same exact error. I need to watch some videos to fully understand why i was getting the error, that way my next model I can start using it correctly.

Thanks for the feedback

Almost what I was looking for. The side on the right is correct, but I was looking for the side on the left to go all of the way through without the little lip. I was able to get what I needed from the post below yours but I truly appreciate the help. Thank you very much!

Had I seen @davebYYPCU 's reply before hitting Post I would not reply. Thin Extrude just didn't came to my mind and I did a needlessly long workflow. That's why you can't (and you don't need to) follow what I did, and that's why I edited my reply right after posting and seeing his reply. Just take what he suggested, i.e. Thin Extrude, as your solution. You only need to set Offset from left side to 0 mm (instead of -1 mm) since you don't want the lip there.

Then change one side to All (the way through).

Might help....

lol I bet you can't guess how dumb I feel right about now 😂

Thank you for this. I didn't even know there was a different extrude option. Much appreciated

Don’t fuss over it, each Extrude only has about 15 options to choose from, when you add them up.

That is when you should STOP and Attach your file here for guidance - do not continue to try to plow on.

Interacting with Forum users is how I learned Fusion best practices techniques (and several other CAD softwares).
