STL hacking: using fusion360 components to calculate a perfect fit.

Sometimes most of the work is done,... but it's not quite right. Here I present some approaches to tweaking an existing STL in fusion 360 to make it suit your exact requirements

Nice! I like the trick to get the circle. One thing fusion does quite well is rebuild a face, so you can take any flat surface, select one of the triangular faces, hit delete and it will remove all of the triangular faces on that surface, replacing them with a single face. A little tricky to explain so I recommend playing with deleting faces. It won't replace your technique for getting a perfect circle but it's really useful for cleaning up other flat surfaces on STLs. Once cleaned up it can make it much easier to work with other tools.

I should probably play more with the face manipulation. I feel like I sometimes struggle to get things back to a coherent solid. But you're right, in a lot of cases I'm sure deleting weird faces and having it just repatch is a fast way to fix things up.

Yes, this. ☝🏻 On any flat surface just deleting a single triangle will give you the same results with far less steps to do and saving your timeline.

❤Great hack. Mahalo for sharing.

On my side i use blender, you just select the face, extract, flat them and bam you got the dimension. Wish fusion could manipulate vertex, edge and face finger in the nose like that.
