Martin, Thank you very much for all the in-depth information you put into this answer for me. It is very helpful. I have 3D Printed this bugle. Unfortunately, while it prints great when flat, it has a horrible line down the center that variable print layer doesn’t fix. When printing vertically, it always has this pinch that turns the first torus into a bowtie. I can see why it happens. There is something in the underlying geometry that you can see it. When it tries to put a small seam there, it messes it up. Even when the seams are placed in the back it still pinches and creates a bow tie. I’ve done a lot of different things to try and fix it, including breaking it apart and fixing the toruses to the main body and then rejoining it. Out of frustration. I decided retopologizing it, or making it from scratch, was the answer. The general form of this bugle is ideal. It’s just been a frustrating project.
I probably am the one that applied the rotation. I didn’t realize it was off and I was trying to make the mirror work. Good lesson. Thank you for the workflow. I will try it.
Omar, thank you for the link to the screw modifier. I know about it, i just haven’t tried using it yet. I will do both, retopo it and model it from scratch.
Again, thank you both for your help. I greatly appreciate it.
