hello I'm new to modeling and i am having a problem and I cant fix it would you be able to help and its has been only a problem with the threaded stuff I've been doing
thread not showing on Cura
Helical geometry is very computationally expensive (slows down your computer if a bunch of them) - therefore we generally show as cosmetic and specify the actual thread size on the 2D drawing documentation. (Also, on small fasteners the distance between crest and root is so minor that it just appears as black "blob" when printing sheet of paper.)
With 3D printing however, we do need to actually have modeled threads.
So as we can observe in the images above - your stated issues was that you could not see threads in your Cura (because there are none), but with careful observation you should have also noted that there weren't really any threads in you Fusion image either.
