How to join two perpendicular sketches into a pyramid-like shape including a curved end?

filloax — Sun, 29 Dec 2024 14:33:25 GMT

Hi, I have the sketches pictured in the following, I am trying to "connect" the sides to form a pyramidish 3d shape. I'm a total newbie to Fusion, so I'm not sure how to do the actual 3d part.

For context: my plan is to make a 4-pointed star shape inside of a ring, with a slight curved fillet joining the points to the ring edge. Currently I'm trying to make a single point of the star, and after finishing it in 3d mirroring it three times for the rotation.

How could I turn these sketches into an actual 3d shape? I think I could use Loft for the non-curved part (from the large section to the small section), but when I try to select the polygon in the large section it selects only a quarter of it delimited by the lines so I'm not sure how to do that either.

patch tool within surfaces, select patch, choose the sides, and it will connect them. end of

I will share my model once I load it up

Thanks! Does that work with the small curved part too?

for small curved parts , yes however it would require something called a guide rail, if you provide the file for this request i can show you what you need to do, or if it is the original file can you specify where it is.

Sorry for the delayed reply, just doing coursework

Happy new year regards

Ah the file is attached in the first post, it's supposed to be f3d format right?

are you looking for something like the attached?

Actually yes, that is exactly what I am trying to do thanks

you might note that

-I didn't use any 3d sketches (you generally want to use 2d unless you HAVE to have a 3d sketch)

-no surface tools where used (patches)

-I took advantage of front to back symmetry, less work.

let me know if you have questions about the model.

What do you mean by 3d sketches? On planes different than the XY one?

Also, if so, how did you make the 3d shape for the star with the edge in the middle?

I could be wrong but I think @laughingcreek is reffering to sketches that are "interlinked" in one connected sketch that is on multiple planes.

by a 3d sketch, I mean a sketch where some (or all) of the sketch articles are not on the sketch plane. the sketch plane can be on any plane (xy, xz, yz, construction, face of a body, etc...). as long as everything remains on that plane, it is considered a 2d sketch.

... how did you make the 3d shape for the star with the edge in the middle?

the loft goes from the profile in sketch1 to the point in sketch2. the "edge" is created by the loft.

Got it thanks. And also then I wasn't even aware 3d sketches were an option, lol
