UPDATE:
The Fusion360 team announced today that they will not be removing STEP export from the free version of Fusion360 because it would have impacted the hobby community. I don’t use that format myself, but it is nice to see that they’re listening to feedback!
As far as I can tell, shots were fired and the writing is on the wall.
When I finish a model in Fusion 360, I don’t use cloud rending to create or export the STL file. I first save the finished model then right click over the body name in the browser. Select “Save as Mesh” and pick STL(binary) for the file type, set the other attributes in the dialog box, then click save. A dialog box will pop up waiting for you give it a file name and where to save the file. That’s all there is to creating a STL file without cloud rendering…it’s also much, much faster. Hope this helps.
