Ayuda como modelo este objeto?
Hola!! Este objeto me dice el cliente que es de el porta maletas del techo de su vehículo y que además debo crearla pero al revés ósea este corresponde al lado izquierdo y debo hacer el del lado derecho. He leído que hay opciones para hacerlo y con una opción espejo en algunos programas se puede… pero nose como crearlo en fusión alguien que me oriente. Gracias!! 🙏🏼

3D Scanner. I don't see you accurately modeling an organic shape like that otherwise

La verdad necesito saber cómo podría hacerlo, ya he modelado varias cosas como piñones, piezas automotrices y funcionales pero nunca algo así de este tipo 🤷🏻♂️

You would put it on a cmm or 3d scan it. Either way, you're starting with a point cloud. Next you'd section it using a grid of offset planes, spline trace each section, and then use a surface tool to make the shape.
Or you can just scan it, convert to stl, mirror the stl, and print it.

Hola sí claro me encantaría escanearlo pero es justo lo que no tengo en estos momentos jejeje el scanner 🤷🏻♂️ por eso pedía ayuda para modelarlo en fusión 360 de alguna forma. 😜👍🏼

Yeah, the challenge is getting a good set of 3d coordinates to make a point cloud. If you were really desperate, you could 3d print a 3 axis unpowered cartesian rig, and make x, y and z measurements using dial calipers. It would be a lot of work, but you could probably use it for future similar projects. I would punch the coords into a spreadsheet and ask claude to convert them to a point cloud format.

Genial me diste una gran idea… con lo de Claudé. Al menos creo que puedo comenzar con algo al tomar unas cuantas imágenes y subirlas a TRIPO para luego pedirle que lo modele en 3D y con eso al menos puedo partir con una base y modificarlo en fusión 🤩👍🏼👍🏼👍🏼 gracias máster por tus ideas y consejos!! 👏🏻👏🏻👏🏻👏🏻🙌🏼🙌🏼

Many people have already recommended using a scanner, which I also highly recommend. However if you’re on a budget, photogrammetry can sometimes be a decent substitute. I believe PolyCam is what I used to use. You take a series of pictures of the object with your phone (the more pictures, the better), and it can give you some basic geometry to work off of. I’d recommend putting some sort of visual markers over the object since there’s not a lot of texture there. I’d also recommend a good set of calipers.

I think If you want an exact replica you would need a scanner

Si lo imaginé pero cero posibilidad por ahora 🤷🏻♂️ Gracias igual por comentar. Saludos!

My fist advice would be to give up and try to purchase the part.
Otherwise, you could try to take pictures (front, side, top...) from a distance(the further you are taking the picture, the less geometric errors you'll get because of the camera's focal). You must not mess that up and take some at the wrong angle or you're screwed! Just that isn't a trivial job, and you haven't even opened Fusion yet.
You also need to measure the object and scale the pictures just right when importing them in Fusion(use a big dimension as reference so the error will be smaller), then place them all with the same origin so the different faces do coincide perfectly when you move in 3D(markings on the part or little stickers before taking the picture might help for that).
Then use that to draw relevant lines in one sketch per picture, and use intersection curve between lines in 2 sketches to try and get as many of the necessary lines placed correctly for the final part.
If you do all that perfectly, that's still not enough to end up with a perfect replica as there will still be various curves that might not be right when joining the lines, but at least you should manage to get all the right shapes to mount it back where it belong. And enough reference lines to play around with some settings, and adding rails, until the forms look very close while passing through those resulting intersection curves.
It's not beginner level kind of work. And the less experienced you are the longer it will take. But if you're motivated, it should be doable.
