Fusion 360 - Threads Not Exported to STL

There is one thing that I always have problems with, so hopefully by writing this short blog post I'll remember more often. That problem is creating threads properly. Usually I noticed after I have already printed the part. Always remember to choose the "Modeled" check box. I wish I could make this the default.

Also, if you need to remove part of the hole after the threads in the timeline, you'll have thread remnants, so move the threads to be later in the timeline, then "Cut" the hole.
