Modify an Stl file in Fusion 360
One of my most popular videos is the above one teaching how to modify an STL file in Fusion 360. There seems to be a high demand of wanting to edit downloaded stl files from Thingiverse or any other file sharing site. Most of you can probably relate. You download a file and need to simply tweak a tiny part to make it fit your application.
Fusion 360 actually makes this pretty simple with the introduction of the Mesh environment and the ability to convert a mesh into a brep. Once converted to a brep, you can then proceed to edit the design as you would any solid.
You do have to be careful however, a file with too many facets (over 10,000) may give you trouble. To see how to address the issue of modifying an stl file with a high number of facets check out this tutorial on Modifying a High Poly STL in Fusion 360.
