As you can see from the image, after doing the sweep with the triangle, and applying the Boolean cut operation - the cut only removed the left half of the triangle. Any idea what is going on, and how to fix this?

Re: Bad cut with making threads
You are adding thread on tapered surface .
Your triangle profile is in tapered surface, modify it to go out of tapered surface to see the cut properly(correctly). Hope this helps.

Re: Bad cut with making threads
Manage 0.3mm to right for the sketch of the cylinder , or to left for the triangle , and all is perfect , especialy for the begening of the thread to the chanfer

Re: Bad cut with making threads
If you work in PartDesign, you should use a PartSesign subtractive pipe to create the thread.

A tapered thread with more problems
I fixed the taper problem, as you can see from trans_to_fittings2 and got exactly the threads I wanted. However, when I added a fillet to the outer radius and a small cylinder to the outer rim, everything changed & I lost my threads.
It did tell me that I was working with an inactive form. What does that mean & how do I fix that?
Where did my threads go & how do I get them back?

Re: A tapered thread with more problems
I have found it's best to add the thread instead of trying to cut it out. I also added a starter to the thread. I changed many dims so this is an example.

erase Cut , do the small Pad , the chanfer , and finish by Cut , if you need add some other op , allway finish by Cut
