I do threads for many years in Sketchup - worst program for 3D printing needs most say but does what I need.
Whenever I create a thread from scratch I use a spiral with the matching pitch and extrude the thread profile around it.
Results in a very nice control of the amount of triangle in the resulting model - Sketchup does not do true circles, only line interpretations.
I abuse this ‘flaw’ to use a number of sides that is doable in terms of print resolution.
Tiny edges and such are smoothed out by the slicer, means there is no need to start with 180 sides for a 6mm bolt…
Getting a thread profile that not just works on screen but is properly printable is not impossible, quite easy actually if you know how your overhangs turn out when printed.
What often is not though if creating longer threads by simple stacking sections.
If you encounter geometry issues when stacking your thread to get the required length try this:
Check where this is a proper junction point - like for those vertical lines over the pitch in your image.
Make this height the first cut and move up vertically to get to the next line in the same spot for the second cut.
Like this you have perfectly matching geometry.
In fusion though you can create custom threads with a few clicks, might be worth checking these tools to create some profiles for your printing needs ?
