I would really like to take advantage of the vast library of models made for OpenSCAD in fusion 360. In particular, a lot of people have made some really good parametric double helix involute gears for OpenSCAD and I would love to pull them into Fusion360 in a format other than STL (which slows Fusion 360 down to a crawl vs having a proper solid model).
