Wrap a sketch around a sphere.

[Anonymous]

Hi. I have made a 2d sketch and i want to wrap it around a sphere and then extrude it. The sphere has a radius of 50mm, so the surface area is 31,415.927, I have square rooted this so i can find the sides of the sketch square. I have attatched a photo as a reference for this. Please help. The 2D sketch and the sphere

I'm afraid you'll need to do a bit more math 😀  This thread may give you a hint.

Fusion 360 can do this - despite what most people will tell you. You need to use the programming interface - Fusion 360 API. (EDIT: As TrippyLighting writes, it functionally means that for most users it is simply not feasibly)

Ben Gruver has done it here:

A plane does not just magical fly onto a sphere - you need a projection, and there are many many different ways to do that:

As I see it, you will probably want to preserve angles and distances, but that is just not possible.

I would still maintain that Fusion 360 cannot do this because that applies to 99.99% of Fusion 360 users, who naturally would be looking or a set of tools available through the UI and I find that perfectly reasonable.

Learning Python or C++ and also familiarizing oneself with the Fusion 360 API takes substantial time and might not be worth the investment. That is a personal choice!

I have a sphere, I'm using Fushion 360 version 2.0.10032 on macOS 10.16.0

In a sketch I have a triangle that I want to wrap onto the project onto the sphere, how to I do this?
